Description: SYSTEM FOR AND METHOD OF PROCESSING DATA, AND APPARATUS AND METHOD OF SENDING AND RECEIVING DATA Technical Field The present invention relates to a system for and a method of processing data to send data to and receive data from an external device, and an apparatus for and a method of sending and receiving data, and more particularly to a system for and a method of processing data and an apparatus for and a method of sending and receiving data, which are preferably applicable to a system using a video game machine and a portable information communication terminal. Background Art Conventional video game machines such as video game apparatus for home use operate by running an application program in a video game machine unit based on game data recorded in a recording medium or an auxiliary memory to play a video game such as a competition game, for example, accord- ing to instructions entered by the game player via a manual controller. Such video game machines are finding widespread use at home. Many video game machines generally have an excellent data processing capability for processing image and audio data so that the game player or user can experience complex and realistic images and sounds. Specifically, the data processing capability of conventional video game machines makes it possible to display complex game characters and produce realistic sounds for the video game, and can provide more sophisticated images and sounds than those produced by existing computers . Though the conventional video game machines have the excellent data processing capability, however, they remain an apparatus for executing an application program to play a video game. There have heretofore been proposed systems of interconnected master and slave units for sending and receiving data therebetween. The data sent and received between the master and slave units are merely ordinary image and sound data. It has not been attempted to supply an application program to be executed by the slave unit from a recording medium that belongs to the master unit. It is therefore an object of the present invention to provide a system for and a method of processing data and an apparatus for and a method of sending and receiving data, which are capable of sending and receiving data between a master unit and an external device via a slave unit. Disclosure of Invention A system for processing data according to the present invention has a master unit for processing data and a slave unit removably connected to the master unit and having a communication means. A communication means control program, which the master unit has acquired with a data supply means , for enabling radio communications between the slave unit and an external device having a radio communication function is supplied from the master unit to the slave unit by the data supply means, and the slave unit stores the supplied communication means control program into a memory means . When the communication means control program supplied the master unit to the slave unit is run by the slave unit, data can be sent and received between the master unit and the slave unit via radio communications . By replacing the slave unit for each different external device, the master unit can perform radio communications with a variety of ex- ternal devices. Accordingly, the system for processing data allows data to be sent and received between the master unit and the external device via the slave unit. In the system for processing data, furthermore, since the communication means control program is supplied from the master unit to the slave unit , the communication means control program does not need to be resident in the slave unit , and hence computational resources of the slave unit can effectively be utilized. In the system for processing data, the master unit has a processing means for processing input data. Data which the slave unit has received from the external device are supplied as input data to the master unit, and the input data are processed by the processing means to produce proc- essed data. The processed data are then sent from the master unit to the external device according to the communication means control program of the slave unit. Consequently, the system for processing data according to the present invention can process data at high speed in a real-time fashion based on the data processing capability of the master unit. For example, image data from a digital camera or a per- sonal computer which serves as the device 4 with the radio function that is the external device are sent via the portable computer 3 to the video game machine 2 as the master unit which has a very high image data processing capability. The image data are processed by the video game machine 2. The processed image data are sent via the portable computer 3 back to the digital camera or the personal computer as the device 4 with the radio function. Therefore, images based on the processed image data can be viewed on the digital camera or the personal computer. In a method of processing data according to the present invention, a slave unit having a memory means is removably connected to a master unit for processing data, and a communication means control program, which the master unit has acquired, for enabling radio communications between the sla- ve unit and an external device having a radio communication function is supplied to and stored in the slave unit. Then, the slave unit and the external device send and receive data therebetween via a communication means. In the method of processing data, the communication means control program is supplied from the master unit to the slave unit, and run by the slave unit for allowing data to be sent and received between the master unit and the external device via the slave unit. An apparatus for sending and receiving data according to the present invention has a communication means for sending data to and receiving data from an external device having a radio communication function, and a memory means for storing inputted data, and is supplied with a communication means control program for performing radio communications with the external device from a data processing apparatus. Since the apparatus for sending and receiving data is supplied with the communication means control program from the data processing apparatus, the data sending and receiving apparatus can perform radio communications with the external device. In a method of sending and receiving data according to the present invention, radio communications with an external device having a radio communication function are performed according to a communication means control program supplied from a data processing apparatus, data received from the external device are transferred to the data processing apparatus, and processed data inputted from the data processing apparatus are sent to the external device. Because radio communications with the external device can be performed according to the communication means control program supplied from the data processing apparatus for allowing communications with the data processing apparatus, data can be sent and received between the data processing apparatus and the external device. The above and other objects, features, and advantages of the present invention will become more apparent from the following description when taken in conjunction with the accompanying drawings in which preferred embodiments of the present invention are shown by way of illustrative example.

Best Mode for Carrying Out the Invention A first embodiment of the present invention will be described below with reference to FIGS. 1 through 12. Accord- ing to the first embodiment, the principles of the present invention are applied to a data processing system 1 capable of sending data to and receiving data from an external device 4 with a radio function. As shown in FIG. 1, the data processing system 1 com- prises a video game machine 2 serving as a master unit for processing data, i.e., a data processing unit, and a portable computer 3 serving as a slave unit . The portable computer 3 is detachably inserted in the video game machine 2. The video game machine 2 is constructed as a video enter- tainment system which executes program data recorded in a recording medium (not shown) to play a video game or the like. The portable computer 3 is constructed as a PDA (Personal Digital Assistant) having a radio communication function. The data processing system 1 is arranged as shown in FIG. 2 and communicates with the device 4 with the radio function. In the data processing system 1, the video game machine 2 comprises a video game machine hardware layer 10 and a software layer for controlling the video game machine hardware layer 10 and performing communications with the portable computer 3, the software layer comprising a communication application 20 and a serial communication driver 30 included in the communication application 20. The portable computer 3 comprises a PDA hardware layer 40 and a software layer for performing a communication process in the PDA hardware layer 40, the software layer comprising a communication application 50, a serial communica- tion driver 60, and a radio communication driver 70. The device 4 with the radio function, which sends data to and receives data from the data processing system 1 via radio communications, comprises a device hardware layer 80 and a software layer for performing a communication process in the device hardware layer 80, the software layer comprising a communication application 90 and a radio communication driver 100 included in the communication application 90. In the present invention, the wording "radio communica- tion(s)" is defined to mean wireless communication s) in the frequency range from around 20 Hz to 800 THz (terahertz), i.e., the frequency range from audio frequency to visible light frequency, including radio frequency and infrared frequency. As shown in FIG. 3, the video game machine hardware layer 10 comprises a CPU 11 functioning as a data supply means for acquiring and supplying data, an input block 12, a recording medium block 13, a main memory 14, a graphic processor 15, a functional block 16, and a serial communication block 17. These components of the video game machine hard- ware layer 10 are connected to a bus 18. As shown in FIG. 4, the PDA hardware layer 40 comprises a radio communication block 41 as a communication means for sending data to and receiving data from the device 4 with - li the radio function, a nonvolatile memory 42 and a working memory 43 both as a memory means for storing entered data, a serial communication block 44, a CPU 45, an input block 46, a display block 47, and a functional block 48. These compo- nents of the PDA hardware layer 40 are connected to a bus 49. The input block 12 of the video game machine hardware layer 10 is arranged to function as a manual input controller. Therefore, the input block 12 allows the user to enter various items of information into the video game machine 2. The input block 12 also allows data to be processed in the video game machine 2 according to a control input action entered by the user. The recording medium block 13 serves as a block for reading various data recorded in a recording medium or the like (not shown). For example, the recording medium comprises a CD-ROM or the like. The recording medium block 13 is controlled by the CPU 11 to read data from the recording medium which stores communication means control programs in- eluding communication applications and drivers that enable the portable computer 3 and the device 4 with the radio function to communicate with each other via a radio link. Specifically, the recording medium block 13 reads data from the recording medium which stores the communication applica- tion 50 and the radio communication driver 70 shown in FIG. 2. The main memory 14 is a memory for storing various data. For example, the main memory 14 stores the communica- tion application 20 as the software layer of the video game machine 2. The main memory 14 also stores data sent from the portable computer 3 via the serial communication block 17. The graphic processor 15 serves as a processor for effecting image processing on entered data. Specifically, the graphic processor 15 effects graphic processing on images to be displayed on a display unit (not shown) . More specifically, the graphic processor 15 performs a polygon graphic processing process. The functional block 16 is arranged to perform other functions than the above blocks, and may comprise, for example, a power supply block (not shown) and a connection block for connection and a nonvolatile memory card system as a re- cording medium. The serial communication block 17 has a function to effect serial communications with an external device. The serial communication block 17 has terminals (not shown) electrically connectable to the serial communication block 44 of the portable computer 3, for example. The video game machine 2 can thus send data to and receive data from the portable computer 3. The serial communication block 17 sends and receives data according to the serial communication driver 30 shown in FIG. 2. The CPU 11 has a function to control the above blocks of the video game machine hardware layer 10. For example, the CPU 11 holds the communication application 50 and the radio communication driver 70 recorded in the recording me- dium in the main memory 14 of the video game machine 2, controls the communication application 50 and the radio communication driver 70 when they are supplied to the portable computer 3, and controls data inputted to and outputted from the portable computer 3. The CPU 11 also has a function to process and edit data. Furthermore, the CPU 11 controls the blocks according to programs of the software layer. The video game machine 2 thus constructed is capable of playing a video game based on a program recorded in the re- cording medium such as a CD-ROM or the like. The video game machine 2 allows the nonvolatile memory card system to be removably connected thereto. The radio communication block 41 of the PDA hardware layer 40 shown in FIG. 4 receives data sent from the device 4 with the radio function by way of infrared rays according to IrDA standards or microwaves. The radio communication block 41 also sends data entered from the video game machine 2 to the device 4 with the radio function. At this time, the radio communication block 41 sends and receives data ac- cording to the radio communication driver 70 shown in FIG. 2. Specifically, when the portable computer 3 sends data to and receives data from the device 4 with the radio function, the radio communication block 41 is controlled by the radio communication driver 70, and a radio communication block (not shown) in the device 4 with the radio function is controlled by the radio communication driver 100. The nonvolatile memory 42 is a memory for storing various data. The nonvolatile memory 42 stores a communication device driver supplied from the video game machine 2 for performing communications with the device 4 with the radio function. Specifically, the nonvolatile memory 42 stores the communication application 50 and the radio communication driver 70 shown in FIG. 2. The nonvolatile memory 42 also stores data received from the device 4 with the radio function and data entered from the video game machine 2 via the serial communication block 44. The working memory 43 is a memory for use as a work storage area for storing various data. As with the nonvolatile memory 42, the working memory 43 stores the communication application 50 and the radio communication driver 70, and also stores data received from the device 4 with the radio function and data entered from the video game machine 2 via the serial communication block 44. The serial communication block 44 has a function to perform serial communications with an external device. For example, the serial communication block 44 is electrically connectable to the serial communication block 17 of the video game machine 2 for performing data communications with the video game machine 2. The serial communication block 44 sends and receives data according to the serial communication driver 60 shown in FIG. 2. The portable computer 3 is supplied, via the serial communication block 44, with a com- munication device driver and a communication application for use with the device 4 with the radio function, which are recorded in a recording medium (not shown) loaded in the video game machine 2, i.e., the communication application 50 and the radio communication driver 70. The input block 46 is arranged to function as a manual control input unit (manual control input means). For example, the input block 46 allows the user to enter various items of information. When the portable computer 3 is not connected to the video game machine 2, the device 4 with the radio function can be operated according to a control input action entered via the input block 46. The display block 47 is arranged to function as a dis- play unit for displaying various items of information. The display block 47 displays various character information and image information on a liquid crystal panel (not shown), for example . The functional block 48 is arranged to perform other functions than the above blocks, and may comprise, for example, a power supply block (not shown). The CPU 45 has a function to control the above blocks. For example, the CPU 45 controls the blocks according to various programs of the above software layer. The portable computer 3 receives data sent from the device 4 with the radio function. The portable computer 3 can removably be connected to the video game machine 2 for sending data to and receiving data from the video game machine 2. Furthermore, the portable computer 3 is compatible with the nonvolatile memory card system (not shown) that can also removably be connected to the video game machine 2. In the data processing system 1, the video game machine 2 supplies the portable computer 3 with a program such as the communication program 50 which enables the portable computer 3 to perform radio communications with the device 4 with the radio function according to processing sequences shown in FIGS . 5 and 6. . As shown in FIG. 5, the CPU 11 of the video game machine 2 reads the communication application 50 and the radio communication driver 70 for use with the portable computer (PDA) 3 which are stored in a recording medium such as a CD- ROM or the like, for example, from the recording medium block 13 in step SI. Then, the CPU 11 stores the communication application 50 and the radio communication driver 70 thus read in the main memory 14 in step S2. The CPU 11 starts communicating with the serial commu- nication block 44 of the portable computer 3 via the serial communication block 17 to establish a communication link therewith in step S3. Thereafter, the CPU 11 sends the communication application 50 and the radio communication driver 70 stored in the main memory 14 to the portable computer 3 via the established communication link. To confirm the end of the transmission of the communication application 50 and the radio communication driver 70, the CPU 11 decides whether the communication application 50 and the radio communication driver 70 stored in the main memory 14 have entirely been sent or not in step S5. If the CPU 11 confirms that the communication application 50 and the radio communication driver 70 stored in the main memory 14 have entirely been sent, then the video game machine 2 finishes the process of sending the communication application 50 and the radio communication driver 70. If the CPU 11 confirms that the communication application 50 and the radio communication driver 70 stored in the main memory 14 have not entirely been sent , then the video game machine 2 executes the processing from step S4 again. Concurrent with the above process carried out by the video game machine 2, the portable computer 3 decides whether there is a serial communication connection request from the video game machine 2 or not in step Sll shown in FIG. 6. If the portable computer 3 confirms that there is a serial communication connection request from the video game machine 2 in step Sll, then the CPU 45 of the portable computer 3 starts communicating with the serial communication block 17 of the video game machine 2 via the serial communication block 44 to establish a communication link therewith in step S12. Then, the CPU 45 stores the communication application 50 and the radio communication driver 70 which have been re- ceived from the video game machine 2 via the established communication link into the working memory 43 or the nonvolatile memory 42 in step S13. The processing in steps S12, S13 performed by the portable computer 3 corresponds to the processing in steps S3, S4 performed by the video game machine 2. To confirm the end of the transmission of the communication application 50 and the radio communication driver 70, the CPU 45 decides whether the communication application 50 and the radio communication driver 70 have entirely been received from the video game machine 2 or not in step S14. If the CPU 45 confirms that the communication application 50 and the radio communication driver 70 have entirely been re- ceived from the video game machine 2 , then the portable computer 3 finishes the process of receiving the communication application 50 and the radio communication driver 70. If the CPU 45 confirms that the communication application 50 and the radio communication driver 70 have not entirely been received, then the portable computer 3 executes the processing from step S13 again. In the data processing system 1, the above processing sequences of the video game machine 2 and the portable computer 3 allow the video game machine 2 to supply the port- able computer 3 with the communication application 50 and the radio communication driver 70 for use with the portable computer 3 for thereby enabling the portable computer 3 to perform radio communications with the device 4 with the radio function. A process of sending data from the device 4 with the radio function to the video game machine 2 will be described below with reference to FIGS. 7 and 8. The portable computer 3 runs the communication application 50 and the radio communication driver 70 supplied from the video game machine 2 to be able to perform radio communications with the external device 4 with the radio function. In step S21 shown in FIG. 7, the portable computer 3 decides whether there is a data reception request from the external device 4 with the radio function or not. If the portable computer 3 confirms that there is a data reception request from the external device 4 with the radio function in step S21, then the CPU 45 of the portable computer 3 starts communicating with the radio communication block (not shown) of the device 4 with the radio function via the radio communication block 41 to establish a communication link therewith in step S22. Then, the CPU 45 starts communicating with the serial communication block 17 of the video game machine 2 via the serial communication block 44 to establish a communication link therewith in step S23. The CPU 45 stores data which have been received from the device 4 with the radio function via the established communication link therewith into the working memory 43 or the nonvolatile memory 42 in step S24. The CPU 45 then sends the data stored in the working memory 43 or the nonvolatile memory 42 to the video game machine 2 via the established communication link with the video game machine 2 in step S25. To confirm the end of the reception of the data from the external device 4 with the radio function, the CPU 45 decides whether the data from the external device 4 with the radio function have entirely been received or not in step S26. If the CPU 45 confirms that the data from the external device 4 with the radio function have entirely been received, then the portable computer 3 finishes the process of receiving the data. If the CPU 45 confirms that the data from the external device 4 with the radio function have not entirely been received, then the portable computer 3 executes the processing from step S24 again. Concurrent with the above process carried out by the portable computer 3, the video game machine 2 decides whether there is a data reception request from the portable computer 3 or not in step S31 shown in FIG. 8. If the video game machine 2 confirms that there is a data reception request from the portable computer 3 in step S31, then the CPU 11 of the video game machine 2 starts communicating with the serial communication block 44 of the portable computer 3 via the serial communication block 17 to establish a communication link therewith in step S32. Then, the CPU 11 stores data which have been received from the portable computer 3 via the established communication link therewith into the main memory 14 in step S33. The processing in steps S32, S33 performed by the video game machine 2 corresponds to the processing in steps S23, S24 performed by the portable computer 3. To confirm the end of the reception of the data from the portable computer 3, the CPU 11 decides whether the data from the portable computer 3 have entirely been received or not in step S34. If the CPU 11 confirms that the data from the portable computer 3 have entirely been received, then the video game machine 2 finishes the process of receiving the data. If the CPU 11 confirms that the data from the portable computer 3 have not entirely been received, then the video game machine 2 executes the processing from step S33 again . The above processing sequences allow the data processing system 1 to send the data from the external device 4 with the radio function to the video game machine 2 via the portable computer 3. A process of sending data from the video game machine 2 to the device 4 with the radio function, which is a reversal of the above process of sending data from the device 4 with the radio function to the video game machine 2, will be de- scribed below with reference to FIGS. 9 and 10. The CPU 11 of the video game machine 2 starts communicating with the serial communication block 44 of the portable computer 3 via the serial communication block 17 to establish a communication link therewith in step S41 shown in FIG. 9. Then, the video game machine 2 decides whether there is a data transmission request from the portable computer 3 or not in step S42. The CPU 11 sends data which have been stored in the main memory 14 to the portable computer 3 via the established communication link therewith in step S43. To confirm the end of the transmission of the data to the portable computer 3, the CPU 11 decides whether the data have entirely been sent or not in step S44. If the CPU 11 confirms that the data have entirely been sent, then the video game machine 2 finishes the process of sending the data. If the CPU 11 confirms that the data have not entirely been sent, then the video game machine 2 executes the processing from step S43 again. Concurrent with the above process carried out by the video game machine 2, the portable computer 3 decides whether there is a data reception request from the video game machine 2 or not in step S51 shown in FIG. 10. If there is a data reception request from the video game machine 2 in step S51, then the CPU 45 of the portable computer 3 starts communicating with the serial communication block 17 of the video game machine 2 via the serial communication block 44 to establish a communication link therewith in step S52. The CPU 45 also starts communicating with the radio communication block (not shown) of the device 4 with the radio function via the radio communication block 41 to estab- lish a communication link therewith in step S53. In step S54, the CPU 45 sends a data transmission request to the video game machine 2. The CPU 45 stores data which have been received from the video game machine 2 via the established communication link therewith into the working memory 43 or the nonvolatile memory 42 in step S55. The CPU 45 sends the data stored in the working memory 43 or the nonvolatile memory 42 to the device 4 with the radio function via the established communication link there- with in step S56. The processing in steps S52, S55 performed by the portable computer 3 corresponds to the processing in steps S41, S43 performed by the video game machine 2. To confirm the end of the reception of the data from the video game machine 2, the CPU 45 decides whether the data from the video game machine 2 have entirely been received or not in step S47. If the CPU 45 confirms that the data from the video game machine 2 have entirely been received, then the portable computer 3 finishes the process of receiving the data. If the CPU 45 confirms that the data from the video game machine 2 have not entirely been received, then the portable computer 3 executes the processing from step S55 again. The above processing sequences allow the data processing system 1 to send the data from the video game machine 2 to the external device 4 with the radio function via the portable computer 3. In the data processing system 1, consequently, data can be transferred between the video game machine 2 and the external device 4 with the radio function via the portable computer 3. In the data processing system 1, the video game machine 2 can process data that have been sent from the external device 4 with the radio function via the portable computer 3 to the video game machine 2. A process of processing the data thus sent will be described below with reference to FIGS. 11 through 14. In step S61 shown in FIG. 11, the portable computer 3 decides whether there is a data reception request from the external device 4 with the radio function or not . If the portable computer 3 confirms that there is a da- ta reception request from the external device 4 with the radio function in step S61, then the CPU 45 of the portable computer 3 starts communicating with the radio communication block (not shown) of the device 4 with the radio function via the radio communication block 41 to establish a communication link therewith in step S62. Then, the CPU 45 starts communicating with the serial communication block 17 of the video game machine 2 via the serial communication block 44 to establish a communication link therewith in step S63. The CPU 45 stores data which have been received from the device 4 with the radio function via the established communication link therewith into the working memory 43 or the nonvolatile memory 42 in step S64. The CPU 45 then sends the data stored in the working memory 43 or the nonvolatile memory 42 to the video game machine 2 via the established communication link with the video game machine 2 in step S65. To confirm the end of the reception of the data from the external device 4 with the radio function, the CPU 45 decides whether the data from the external device 4 with the radio function have entirely been received or not in step S66. If the CPU 45 confirms that the data from the external device 4 with the radio function have entirely been re- ceived, then control goes to step S67 shown in FIG. 12. If the CPU 45 confirms that the data from the external device 4 with the radio function have not entirely been received, then the portable computer 3 executes the processing from step S64 again. Concurrent with the above process carried out by the portable computer 3, the video game machine 2 decides whether there is a data reception request from the portable com- puter 3 or not in step S81 shown in FIG. 13. If the video game machine 2 confirms that there is a data reception request from the portable computer 3 in step S81, then the CPU 11 of the video game machine 2 starts communicating with the serial communication block 44 of the portable computer 3 via the serial communication block 17 to establish a communication link therewith in step S82. Then, the CPU 11 stores data which have been received from the portable computer 3 via the established communication link therewith into the main memory 14 in step S83. The processing in steps S82, S83 performed by the video game machine 2 corresponds to the processing in steps S63, S64 performed by the portable computer 3. To confirm the end of the reception of the data from the portable computer 3, the CPU 11 decides whether the data from the portable computer 3 have entirely been received or not in step S84. If the CPU 11 confirms that the data from the portable computer 3 have entirely been received, then the video game machine 2 processes the data in step S85. If the CPU 11 confirms that the data from the portable computer 3 have not entirely been received, then the video game machine 2 executes the processing from step S83 again. After having entirely received the data from the portable computer 3 , the video game machine 2 reads the data stored in the main memory 14. If the received data are image data, for example, the video game machine 2 processes the data to change colors, for example. The video game machine 2 , which also f nctions as a processing means, can process the data according to a programmed sequence. Alternatively, the video game machine 2 can process the data according to instructions entered by the user via the input block 12, which also functions as the processing means. Specifically, when the user presses a button on a controller (not shown) associated with the input block 12, the video game machine 2 can increase or reduce the lightness of image data, for example, depending on the period of time for which the button is continuously pressed. Therefore, the data sent from the external device 4 with the radio function via the portable computer 3 to the video game machine 2 are processed by the video game machine 2. The processed data are then stored in the main memory 14 of the video game machine 2. The processed data can subsequently be sent from the video game machine 2 via the portable computer 3 to the device 4 with the radio function. Specifically, the CPU 11 starts communicating with the serial communication block 44 of the portable computer 3 via the serial communication block 17 to establish a communica- tion link therewith in step S86 shown in FIG. 14. The video game machine 2 decides whether there is a data transmission request from the portable computer 3 or not in step S87. If the video game machine 2 confirms that there is a data reception request from the portable computer 3 in step S87, then the CPU 11 sends the processed data stored in the main memory 14 to the portable computer 3 via the estab- lished communication link therewith in step S88. To confirm the end of the transmission of the data to the portable computer 3, the CPU 11 decides whether the data have entirely been sent or not in step S89. If the CPU 11 confirms that the data have entirely been sent , then the video game machine 2 finishes the process of sending the data. If the CPU 11 confirms that the data have not entirely been sent, then the video game machine 2 executes the processing from step S88 again. Concurrent with the above process carried out by the video game machine 2, the portable computer 3 decides whether there is a data reception request from the video game machine 2 or not in step S67 shown in FIG. 12. If there is a data reception request from the video game machine 2 in step S67, then the CPU 45 of the portable computer 3 starts communicating with the serial communication block 17 of the video game machine 2 via the serial communication block 44 to establish a communication link therewith in step S68. The CPU 45 also starts communicating with the radio communication block (not shown) of the device 4 with the radio function via the radio communication block 41 to establish a communication link therewith in step S69. In step S70, the CPU 45 sends a data transmission re- quest to the video game machine 2. The CPU 45 stores the processed data which have been received from the video game machine 2 via the established communication link therewith into the working memory 43 or the nonvolatile memory 42 in step S71. The processing in step S68, S71 performed by the portable computer 3 corresponds to the processing in step S86, S88 performed by the video game machine 2. The CPU 45 sends the data stored in the working memory 43 or the nonvolatile memory 42 to the device 4 with the radio function via the established communication link therewith in step S72. To confirm the end of the reception of the data from the video game machine 2, the CPU 45 decides whether the da- ta from the video game machine 2 have entirely been received or not in step S73. If the CPU 45 confirms that the data from the video game machine 2 have entirely been received, then the portable computer 3 finishes the process of receiving the data. If the CPU 45 confirms that the data from the video game machine 2 have not entirely been received, then the portable computer 3 executes the processing from step S71 again. The above processing sequences allow the data processing system 1 to send the data from the external device 4 with the radio function to the video game machine 2 via the portable computer 3. After the data have been processed by the video game machine 2, the processed data are sent via the portable computer 3 to the device 4 with the radio func- tion . In the data processing system 1, as described above, the communication application 50 and the radio communication driver 70 for the portable computer 3 which are compatible with the device 4 with the radio function are supplied from the video game machine 2 to the portable computer 3 when required, and then run by the portable computer 3. Therefore, it is not necessary for the communication application 50 and the radio communication driver 70 to be resident in the portable computer 3 , and hence computational resources of the portable computer 3 can effectively be utilized. Since the portable computer 3 is easily removably con- nectable to the video game machine 2, the communication application 50 and the radio communication driver 70 for the portable computer 3 which are compatible with the device 4 with the radio function may be held by the portable computer 3, and the portable computer 3 may be replaced each time the device 4 with the radio function is changed. Consequently, a variety of devices 4 of different types can be connected to the video game machine 2. Even if the memory such as the nonvolatile memory 42 of the portable computer 3 is of a small storage capacity and fails to store entire data sent from and received by the portable computer 3, the portable computer 3 can send and receive a large amount of data by successively sending data to the video game machine 2 or successively receiving data from the video game machine 2. In the data processing system 1 , the portable computer 3 does not need to be connected to the video game machine 1 in use. Once the portable computer 3 is supplied with the communication application 50 and the radio communication driver 70 from the video game machine 2, since the portable computer 3 can run the communication application 50, etc. via the input block 46, the portable computer 3 singly can operate the device 4 with the radio function. Therefore, data from the device 4 with the radio function may be held by the portable computer 3 depending on a control input ac- tion entered via the portable computer 3 , and the portable computer 3 may subsequently be connected to the video game machine 2 for data processing. Thus, there can be constructed a highly efficient system with good portability. In the video game machine 2, the communication applica- tion 50 and the radio communication driver 70 to be supplied to the portable computer 3 do not need to be recorded in a recording medium such as a CD-ROM or the like, but may be acquired via communications with an external source. A data processing system 101 according to a second em- bodiment of the present invention will be described below with reference to FIG. 15. The data processing system 101 has a basic arrangement similar to the data processing system 1 according to the first embodiment, except that two portable computers 3a, 3b are connected to the video game machine 2. Those parts of the data processing system 101 which are identical to those of the data processing system 1 are denoted by identical reference characters, and will not be described in detail below. As shown in FIG. 15, the data processing system 101 comprises a video game machine 2 serving as a master unit for processing data and two portable computers 3a, 3b each serving as a slave unit. The video game machine 2 has two terminals (not shown) in the serial communication block 17, and the portable computers 3a, 3b are removably connectable to the video game machine 2 through those terminals, as with the first embodiment. The portable computers 3a, 3b have been supplied in advance with respective communication ap- plications 50 and respective radio communication drivers 70 which are compatible with respective devices 4a, 4b with a radio function. Each of the portable computers 3a, 3b is structurally identical to the portable computer 3 according to the first embodiment. In the data processing system 101, data can be inputted from the device 4a with the radio function via the portable computer 3a to the video game machine 2, and data can be outputted from the video game machine 2 via the other port- able computer 3b to the other device 4b with the radio function. Specifically, the video game machine 2 and the portable computer 3a can perform the processing sequences shown in FIGS. 7 and 8 to input data from the device 4a with the ra- dio function via the portable computer 3a to the video game machine 2 , and the video game machine 2 and the portable computer 3b can perform the processing sequences shown in FIGS. 9 and 10 to input data from the video game machine 2 via the portable computer 3b to device 4b with the radio function. Therefore, with the two portable computers 3a, 3b connected to the video game machine 2 , the portable computer 3a can transmit input data to the video game machine 2 and the other portable computer 3b can transmit output data from the video game machine 2, independently of each other. In the data processing system 101, consequently, the video game machine 2 and the two portable computers 3a, 3b can be connected to each other to send and receive data. In the data processing system 101, furthermore, data from the device 4a with the radio function can be processed by the video game machine 2. For such data processing, data inputted from the device 4a with the radio function via the portable computer 3a to the video game machine 2 in steps S61 through S66 shown in FIG. 11 and steps S81 through S84 shown in FIG. 13 are processed by the video game machine 2 in step S85 shown in FIG. 13, and the processed data are outputted to the other portable computer 3b and transmitted to the other device 4b with the radio function in steps S67 through S73 shown in FIG. 12 and steps S86 through S89 shown in FIG. 14. At this time, the data may be processed by the video game machine 2 according to a control input action entered by the user via the input block 12. In the data processing system 101, data successively sent from the device 4a with the radio function via the portable computer 3a to the video game machine 2 can be processed by the video game machine 2, and the processed da- ta can be sent via the portable computer 3b to the other device 4b with the radio function and used by the device 4b with the radio function. In the data processing system 101, furthermore, if the device 4a with the radio function can communicate with the portable computers 3a, 3b via radio links, then data successively sent from the device 4a with the radio function via the portable computer 3a to the video game machine 2 can be processed by the video game machine 2, and the processed da- ta can be sent via the portable computer 3b back to the device 4a with the radio function. A data processing system 151 according to a third embodiment of the present invention will be described below with reference to FIG. 16. The data processing system 151 has a basic arrangement similar to the data processing system 101 according to the second embodiment, except that three or more portable computers are connected to the video game machine 2. Those parts of the data processing system 151 which are identical to those of the data processing sys- tern 101 are denoted by identical reference characters, and will not be described in detail below. In the illustrated embodiment, three portable computers 3a, 3b, 3c are connected to the video game machine 2. As shown in FIG. 16, the data processing system 151 comprises a video game machine 2 serving as a master unit for processing data, three portable computers 3a, 3b, 3c each serving as a slave unit, and a connection hub 5 by which the portable computers 3a, 3b, 3c are connected to the video game machine 2. The connection hub 5 is used to provide a sufficient number of terminals if the terminals (not shown) of the serial communication block 17 of the video game machine 2 are fewer than the number of the port- able computers to be connected. The connection hub 5 is connected to a terminal of the video game machine 2 , and a plurality of portable computers are removably connected to the connection hub 5. The terminals of the connection hub 5 and the terminal of the video game machine 2 have electri- cally and physically identical specifications. In the data processing system 151, the three portable computers 3a, 3b, 3c are electrically connected to the video game machine 2 by the connection hub 5. The portable computers 3a, 3b, 3c have been supplied in advance with respec- tive communication applications 50 and respective radio communication drivers 70 which are compatible with respective devices 4a, 4b, 4c with a radio function. Each of the portable computers 3a, 3b, 3c is structurally identical to the portable computer 3 according to the first embodiment. In the data processing system 151, as with the data processing system 101 according to the second embodiment, a portable computer for supplying data to the video game machine 2 and a portable computer for being supplied with data from the video game machine 2 can be different from each other. Specifically, in the data processing system 151, the video game machine 151 and the portable computers 3a, 3b can perform the operation sequences shown in FIGS . 7 and 8 to input data from the devices 4a, 4b with the radio function via the portable computers 3a, 3b to the video game machine 2, and the video game machine 2 and the portable computer 3c can perform the processing sequences shown in FIGS. 9 and 10 to input data from the video game machine 2 via the portable computer 3c to device 4c with the radio function. For such a mode of operation, the user operates the input block 12 to establish the portable computers 3a, 3b as portable computers for inputting data to the video game machine 2, and establish the portable computer 3c as a portable computer for outputting data from the video game machine 2. Furthermore, settings are made in the communication application 50 supplied from the video game machine 2 or another application run by the video game machine 2 to distinguish the portable computers 3a, 3b for inputting data to the video game machine 2 from the portable computer 3c for outputting data from the video game machine 2. Even with plural portable computers connected to the video game machine 2 by the connection hub 5, they can be divided into those for inputting data from external devices with a radio function to the video game machine 2 and those for inputting data from the video game machine 2 to external devices with a radio function, and the different groups of portable computers can input the data independently of each other. In the data processing system 151, consequently, the video game machine 2 and the three or more portable comput- ers can be connected to each other to send and receive data. In the data processing system 151, furthermore, as with the data processing system 101 according to the second embodiment, data inputted from the devices 4a, 4b with the ra- dio function via the portable computers 3a, 3b to the video game machine 2 in steps S61 through S66 shown in FIG. 11 and steps S81 through S84 shown in FIG. 13 are processed by the video game machine 2 in step S85 shown in FIG. 13, and the processed data are outputted to the other portable computer 3c and transmitted to the other device 4c with the radio function in steps S67 through S73 shown in FIG. 12 and steps S86 through S89 shown in FIG. 14. Accordingly, the data inputted from the devices 4a, 4b with the radio function via the portable computers 3a, 3b to the video game machine 2 can be processed by the video game machine 2, and the processed data can be sent via the portable computer 3c to the device 4c with the radio function. In the data processing system 151, the portable computers connected to the video game machine 2 are not limited to three portable computers, but may be as many portable computers as possible. A data processing system 201 according to a fourth embodiment of the present invention will be described below with reference to FIG. 17. The data processing system 201 has a basic arrangement similar to the data processing system 1 according to the first embodiment, except that two devices with a radio function are connected to the portable computer 3. Those parts of the data processing system 101 which are identical to those of the data processing system 1 are denoted by identical reference characters , and will not be described in detail below. As shown in FIG. 17, the data processing system 201 comprises a video game machine 2 serving as a master unit for processing data and a portable computer 3 serving as a slave unit . The portable computer 3 is removably connected to the video game machine 2. The portable computer 3 is connected to two devices 4a, 4b with a radio function for radio communications with each other in a time-division or bandwidth-division fashion. The portable computer 3 has been supplied in advance with communication applications 50 and radio communication drivers 70 which are compatible with the respective devices 4a, 4b with the radio function. In the data processing system 201, the portable computer 3 can receive data from the device 4a with the radio function, and output data from the video game machine 2 to the other device 4b with the radio function. In the data processing system 201, specifically, commu- nication links established between the portable computer 3 and the devices with the radio function are changed such that data from the device 4a with the radio function are received by the portable computer 3 in steps S61 through S66 shown in FIG. 11 and data sent from the video game machine 2 are sent to the other device 4b with the radio function by the portable computer 3 in steps S67 through S73 shown in FIG. 12. In the data processing system 201, consequently, the portable computer 3 and the two devices 4a, 4b with the radio function can be connected to each other to send and receive data. In the data processing system 201, data successively sent from the device 4a with the radio function via the portable computer 3 to the video game machine 2 can be processed by the video game machine 2, and the processed data can be sent via the portable computer 3 to the other device 4b with the radio function and used by the device 4b with the radio function. At this time, the data may be processed by the video game machine 2 according to a control input action entered by the user via the input block 12. A data processing system 251 according to a fifth embodiment of the present invention will be described below with reference to FIG. 18. The data processing system 251 has a basic arrangement similar to the data processing system 201 according to the fourth embodiment, except that three or more devices with a radio function are connected to the portable computer 3. Those parts of the data processing system 201 which are identical to those of the data processing system 1 are denoted by identical reference characters , and will not be described in detail below. In the illustrated embodiment, three devices 4a, 4b, 4c with a radio function are connected to the portable computer 3. As shown in FIG. 18, the data processing system 251 comprises a video game machine 2 serving as a master unit for processing data and a portable computer 3 serving as a slave unit . The portable computer 3 is removably connected to the video game machine 2. The portable computer 3 is connected to three devices 4a, 4b, 4c with a radio function for radio communications with each other in a time-division or bandwidth-division fashion. The portable computer 3 has been supplied in advance with communication applications 50 and radio communication drivers 70 which are compatible with the respective devices 4a, 4b, 4c with the radio function. In the data processing system 251, the portable computer 3 can receive data from the devices 4a, 4b with the radio function, and output data from the video game machine 2 to the device 4c with the radio function. In the data processing system 251, specifically, communication links established between the portable computer 3 and the devices with the radio function are changed such that data from the devices 4a, 4b with the radio function are received by the portable computer 3 in steps S61 through S66 shown in FIG. 11 and data sent from the video game machine 2 are sent to the device 4c with the radio function by the portable computer 3 in steps S67 through S73 shown in FIG. 12. For such a mode of operation, the user operates the input block 12 to establish the devices 4a, 4b with the radio function as devices for inputting data to the portable computer 3, and establish the device 4c with the radio function as a device for being supplied with data from the portable computer 3 in the data processing system 251. Furthermore, settings are made in the communication application 50 supplied from the video game machine 2 or another application run by the video game machine 2 to distinguish the devices 4a, 4b with the radio function for inputting data to the portable computer 3 from the device 4c with the radio function for being supplied with data from the portable computer 3 from each other in the data processing system 251. In the data processing system 251, consequently, the portable computer 3 and the three or more devices with the radio function can be connected to each other to send and receive data. In the data processing system 251, as with the data processing system 201 according to the fourth embodiment, data successively sent from the devices 4a, 4b with the radio function via the portable computer 3 to the video game machine 2 can be processed by the video game machine 2, and the processed data can be sent via the portable computer 3 to the device 4c with the radio function and used by the device 4c with the radio function. A video entertainment system as a specific example of the data processing systems according to the above embodi- ments will be described below with reference to FIGS. 19 through 26. In FIGS. 19 through 26, the data processing system comprising the video game machine 2 and the portable computer 3 (the portable computers 3a, 3b, 3c in the second and third embodiments) is arranged as a video entertainment system which comprises a video game apparatus 301 and a portable electronic device 400. The video game machine 2 corresponds to the video game apparatus 301, and the portable computer 3 corresponds to the portable electronic device 400. Specifically, the CPU 11 and the main memory 14 of the video game machine 2 correspond respectively to a CPU 351 and a main memory 353 of the video game apparatus 301 shown in FIG. 22, and the radio communication block 41, the nonvolatile memory 42, and the CPU 45 of the portable computer 3 correspond respectively to a wireless communication means 448, a nonvolatile memory 446, and a control means 441 shown in FIG. 25. As shown in FIGS. 19 and 20, the video game apparatus 301 reads an application program from a recording medium, and executes the application program according to instructions from the user, i.e., the game player. For example, the video game apparatus 301 executes a game program mainly to proceed with a game, display game images, and output sounds. The video game apparatus 301 has a rectangular casing 302 which houses a disk loading unit 303 substantially centrally therein for loading an optical disk such as a CD-ROM or the like as a recording medium for supplying an applica- tion program such as a game program or the like. The casing 302 supports a reset switch 304 for resetting a video game, a power supply switch 305, a disk control switch 306 for controlling the loading of the optical disk, and two slots 307A, 307B. The video game apparatus 301 may be supplied with an application program via a communication link, rather than being supplied from the recording medium. The portable electronic device 400 and a manual con- troller 320 can be connected to the slots 307A, 307B. A memory card system (not shown) may also be connected to the slots 307A, 307B. The manual controller 320 has first and second control pads 321, 322, a left button 323L, a right button 323R, a start button 324, a selector button 325, analog control pads 331, 332, a mode selector switch 333 for selecting control modes for the analog control pads 331, 332, and an indicator 334 for indicating a selected control mode. The manual con- troller 320 also has a vibration imparting mechanism (not shown) disposed therein for imparting vibrations to the manual controller 320 depending on how the video game proceeds. The manual controller 320 is electrically connected to the slot 307B in the casing 302 by a connector 326. If two manual controllers 320 are connected respectively to the slots 307A, 307B, two users or game players can share the video entertainment system to play a competition game, for example. The video game apparatus 301 may have more or less than two slots 307A, 307B. As shown in FIGS. 21 through 23, the portable electronic device 400 has a housing 401 which supports a manual control pad 420 for entering various items of information, a display unit 430 such as a liquid crystal display (LCD) unit or the like, and a window 440 for wireless communication such as infrared communication with a wireless communication command unit (not shown). The housing 401 comprises an upper shell 401a and a lower shell 401b, and houses a board which supports memory devices, etc. thereon. The housing 401 is shaped so as to be insertable into either one of the slots 307A, 307B in the casing 302. The window 440 is mounted on a substantially semicircu- lar end of the housing 401. The display unit 430 occupies a substantially half area of the upper shell 401a of the housing 401, and is positioned near the window 440. The manual control pad 420 has a plurality of control buttons 421, 422 for entering events and making various se- lections. The manual control pad 420 occupies the other substantially half area of the upper shell 401a, and is positioned remotely from the window 440. The manual control pad 420 is disposed on a lid 410 that is angularly movably supported on the housing 401. The control buttons 421, 422 extend through the lid 410 from its upper surface to its lower surface. The control buttons 421, 422 are supported on the lid 410 for movement into and out of the upper surface of the lid 410. The portable electronic device 400 has a board disposed in the housing 410 and facing the lid 410 as it is closed over the housing 401. The board supports a plurality of switch pressers held in alignment with the respective control buttons 421, 422 when the lid 410 is closed over the housing 401. When one of the control buttons 421, 422 is pressed by the user, it actuates the corresponding switch presser to press a pressure switch such as a diaphragm switch, for example. As shown in FIG. 20, the portable electronic device 400 with the lid 410 being open is inserted into the slot 307A in the casing 302 of the video game apparatus 301. The video game apparatus 301 and the portable electronic device 400 have respective appearances and structures as described above. FIGS. 22 and 23 show circuit arrangements of the video game apparatus 301 and the portable electronic device 400. As shown in FIG. 24, the video game apparatus 301 comprises a control system 350 including a central processing unit (CPU) 351 and its peripheral devices, a graphic system 360 including a graphic processing unit (GPU) 362 for plotting image data in a frame buffer 363, a sound system 370 including a sound processing unit (SPU) 371 for generating music sounds and sound effects, an optical disk controller 380 for controlling an optical disk in which application programs are recorded, a communication controller 390 for controlling signals from the manual controller 320 which enter instructions from the user, and data supplied to and from the memory card 500 which stores game settings and the portable electronic device 400, a bus 395 to which the control system 350, the graphic system 360, the sound system 370, the optical disk controller 380, and the communication controller 390 are connected, a parallel I/O interface (PIO) 396 and a serial I/O interface (SIO) 397 which interface another apparatus. The control system 350 comprises a CPU 351, a peripheral device controller 352 for controlling direct memory access (DMA) data transfer, a main memory 353 comprising a random-access memory (RAM), and a read-only memory (ROM) 354 storing a program such as an operating system or the like for managing the main memory 353, the graphic system 360, and the sound system 370. The CPU 351 controls the video game apparatus 301 in its entirety by executing the operating system stored in the ROM 354. When the video game apparatus 301 is turned on, the CPU 351 executes the operating system stored in the ROM 354 to start controlling the graphic system 360, the sound system 370, etc. For example, when the operating system is executed, the CPU 351 initializes the video game apparatus 301 in its entirety for confirming its operation, and thereafter controls the optical disc controller 380 to execute an ap- plication program recorded in the optical disk. As the application program is executed, the CPU 351 controls the graphic system 360, the sound system 370, etc. depending on instructions entered from the user for thereby controlling the display of images and the generation of music sounds and sound effects. The CPU 351 corresponds to the CPU 11 of the video game machine 2, and recovers data received by the portable electronic device 400 and sent thereto. The graphic system 360 functions as the graphic proces- sor 15 of the video game machine 2. The graphic system 360 comprises a geometry transfer engine (GTE) 361 for performing coordinate transformations and other processing, a GPU 362 for plotting image data according to commands from the CPU 351, a frame buffer 363 for storing image data plotted by the GPU 362, and an image decoder 364 for decoding image data compressed and encoded by an orthogonal transform such as a discrete cosine transform. The GTE 361 has a parallel arithmetic mechanism for performing a plurality of arithmetic operations parallel to each other, and can perform coordinate transformations, light source calculations , matrixes , or vectors at a high speed in response to a request from the CPU 351. Specifi- cally, the GTE 361 can calculate the coordinates of a maximum of 1.5 million polygons per second for a flat shading process to plotting one triangular polygon with one color, for example. With the GTE 361, the video game apparatus 301 is able to reduce the burden on the CPU 351 and perform high-speed coordinate calculations. According to an image plotting command from the CPU 351, the GPU 362 plots a polygon or the like in the frame buffer 363.
