Abstract

PURPOSE: To perform branch simply without degradation of a processing speed by using a part of a scratch-pad memory as the address memory part for branch trace and by performing branch trace in the memory cycle by micro program control.
CONSTITUTION: A current executing branch instruction address is stored in address memory part BTAS for trace of scratch-pad memory 102, and condition truth or condition failure of the conditional branch instruction is decided by branch check circuit 117, and decision signal BR is generated from circuit 117. The branch instruction address is stored in memory part BTAS of memory 102 through selector 109 while the micro program for the branch instruction is executed in operation circuit 101 and data is supplied to other memory address register 103, program status word register 104, etc., and the branch instruction address from memory part BTAS is selected by selector 122 and is applied to control memory part 118 in case of branch condition truth.
