Abstract

PURPOSE: To enable a data processing unit controlled by microprograms to process data at a high speed with its delay time shortened through small-sized hardware, by making it possible to operate processes in the divided cycle of its machine one.
CONSTITUTION: The data processing unit with executes instructions through the control of microprograms is provided with microprogram control parts 1 and 2 different in cycle time. This control part 1 is provided with control memory 1 operating in cylce T1, microinstruction register 3, decoder circuit 5, and address control circuit 10, and control part 2 is with control memory 2 operating at cycle T2= T1/2, register 4, decoder 6, and control circuit 11. Then, control circuits 10 and 11 control memories 1 and 2 independently, and arithmetic execution circuit 7 supplied with the outputs of decoders 5 and 6 performs the combinational arithmetic of the outputs of control memories 1 and 2.
