Abstract

PURPOSE: To simplify the constitution of hardware, by grouping the content of operation processing required for the processing of one instruction according to the types, and outputting the signal of the function control of the operation processor through the selection of this group.
CONSTITUTION: Either one or A+1 function or A+B function signal is selected with the selector 11, and the content of the instruction register is decoded or encoded with the decoder/encoder 12. Further, either one of the A function or B function is selected with the selector 13 by the control signal C2 from the instruction register, special processing for instruction is made with the special processing section 14, the content of each operational processing is fed to the selector 15 on the types, the block sectioned on the dynamic control signals C3 and C4 is selected with the selector 15 to output the function control signal FC to the operation processing unit.
