Abstract

PURPOSE:To shorten the processing time considerably, by previding a register for holding information of an operation exeucting instruction, waiting registers for holding instruction before execution, and a means which compares the executing instruction with the instruction before exection to execute the instructions in order. CONSTITUTION:Instruction information is set to a fetch register 10. On condition that register interference check circuits 13-1 and 13-2 indicate non-register interference, a waiting register making control circuit 11 transfers instruction information of the fetch register 10 to a waiting register 12-1 or 12-2. A selector 14 selects the waiting register 12-1 or 12-2 by the control of a selecting control circuit 19. On condition that refister interference check circuits 18-1 and 18-2 indicate non-redister interference, an instruction transmission control circuit 15 transfers the output of the selector 14 to an adding register 17 or a multiplying register 16 and transmits start information for an operation processing part simultaneously.
