Abstract

PURPOSE: To shorten a waiting time required after executing a branch instruction by allowing an instruction word reading part to read out the succeeding instruction word at the succeeding clock when an instruction decoding part decides the branch instruction.
CONSTITUTION: When the instruction decoding part 3 decides a branch instruction, a branch objective instruction cache memory 8 receives an operand address specifying part consisting of a direct instruction word modification register number part 12 and an operand address deforming part 13 from the decoding part 3 and sends the copy of a part of the contents stored in a storage means 1 to the decoding part 3 based upon the operand address specifying part. Thereby, a branch objective instruction can be quickly read out from the memory 8. Consequently, the waiting time required after executing the branch instruction can be shortened.
