Title: Binary floating point data compression and expansion system
Inventor: WAKAMATSU KAZUYUKI
IPC: H03M7/50
Filed: 1990-11-15
Abstract: PURPOSE:To obtain the compression effect by deciding a sign of an exponent part of binary floating point data before compression, setting '1' to the exponent part when the exponential part before the compression is negative and setting '0' to the exponent part when the exponential part before the compression is positive. CONSTITUTION:A binary floating point data compression and storage device 2 extracts at first a sign of a binary floating point data before compression and sets its sign to a code part 31. Then the device 2 decides a sign of an exponent part 33 of the binary floating point data before compression and sets '1' to the exponent part when the exponent part 33 before the compression is negative and transfers the absolute value of the exponent part to a work area with right justification. Moreover, the device 2 sets '0' to the exponent part when the exponent part 33 before the compression is positive and transfers the absolute value in a similar way to the case with the negative exponent part. Then a mantissa part 34 before the compression is transferred to the work area, and an effective data length resulting from obtaining by suppressing a heat byte whose value is '0' in binary data in the work area is calculated and the result is set as a data length of the mantissa part 34. Thus, the data after its head byte is suppressed is set as the mantissa part data in this way.

Title: Memory area expanding system
Inventor: MURAI MASAMI
IPC: G06F12/06
Filed: 1986-12-26
Abstract: PURPOSE:To essentially expand a limited address for a main memory device without using a means such as the exchange of a microprocessor, by superposing an address for an input/output device on the address for the main memory device. CONSTITUTION:Simultaneously with the switching of a task, an address switching device 3 is operated, and an address line 5 is switched to a picture memory 4. Since the switching of the address line 5 is executed simultaneously with the switching of the task, a task B accesses to the picture memory 4 even when the fact that the main memory device 2 exists on the same address as that of the picture memory 4 is not information to the task B, and it can output an image output. In such way, since a task A and the task B can use the same address for another application independently without changing the processing of the task, it is possible to obtain the same effect as the one in which the main memory device can be expanded by the capacity of the picture memory 4.
