Title: Logical operation controller
Inventor: MATSUMOTO YOSHIHIRO
IPC: G05B19/05
Filed: 1979-02-28
Abstract: PURPOSE: To realize a miniature, low-priced and efficient logical operation controller with memory capacity reduced by operating one-bit logical operation units in parallel and then by controlling the clock signal of each logical operation unit.  
     CONSTITUTION: Program counter PC sends an address signal for an instruction to be executed to program memory PM stored with executive instructions to read the instruction, which is supplied to one-bit logical operation units ICU 1 WICU 3 . Then, ICU 1 WICU 3  put arithmetic into effect and write or read the results into or from data memory DM at an address position indicated by PM by way of buffer BUF. When one of ICUs sends a jump instruction, clock signals of two other ICUs are cut off and their following operations are inhibited. Once a return instruction is sent out, the transmission of the clock signals are restarted and the interrupted operations of ICUs are also restarted. As a result, the need for a memory for no- operation instructions is eliminated and the memory capacity can be reduced, so that the operations can be made efficient.
