Abstract: PURPOSE: An eight-bit RISC based microcontroller including a paging register which is combined with the contents of the logical sixteen-bit register provides an even greater addressing range and it enables directly reading and writing to any bit position within the register file with a single instruction. CONSTITUTION: A register file includes a second arithmetic and logic unit ALU-2 dedicated to the register file to facilitate sixteen bit computations involving the logical sixteen bit registers. The arithmetic and logic unit ALU-2 is a sixteen bit design, customized to provide specific operations typically required of indirect address pointers. The ALU-2 has a first input which is fed by the data-out bus(104) of the register file. The ALU-2 has a second input which is fed by a selector(110). The selector selects a numeric value from among three choices: a numeric value of -1, a numeric value of +1, and a constant V. The output of ALU-2 feeds back to the X, Y, Z registers on the data-in bus(102), allowing for the contents of the registers to be updated. A MUX(114) is coupled to the bus interface(14') of the register file. One input of the MUX is coupled to the output of the ALU-2, while a second input of the MUX is coupled to the data-out bus. This arrangement allows the MUX to selectively output data either from ALU-2 or from the register circuitry(100).

Abstract: PURPOSE: A method and system are provided to efficiently transmit information in an environment related to a computer by expressing respective bits by prescribed frequencies, simultaneously modulating them and transmitting the waveforms through an information processing bus, thereby improving information transferring method in computer-related environment. CONSTITUTION: A register (145) has four bits (b1-b4) and the respective bits are expressed by the prescribed frequency values of (1, 3, 6 and 9) MHz at ('1', '0', '1', and '0'), Thus, the prescribed frequencies with which the respective bits are obtained through (VCO 147) are given to a modulator (149). The prescribed frequencies of the respective bits are generated only when the bit is '1' and are not generated when the bit is '0'. Thus, (b1 and b3) when the bits are '1' are expressed by the frequencies of (1 and 6) MHz and are inputted to the modulator (149). Then, bits (b2 and b4) are '0' and therefore (VCO 147) does not frequency-express them. The carrier frequencies of 100 MHz of an oscillator (151) are simultaneously inputted to the converter (149) and a carrier (153) is generated. The carrier band width of the result is (100-110) MHz established from the minimum value to the maximum value of (VCO 147) and it is transmitted through an information processing bus (131).
