PURPOSE:To execute conditional branching with high flexibility and at a high speed by designating optionally with an instruction one of plural condition code memory means to which the information is set together with readout of said information. CONSTITUTION:A process B is first executed and a condition code register is designated to set the condition code produced by the processing which is executed by a CCRP field of an instruction word. Then the condition code is set to a condition code register CCR0 by the process B. Then a process A is executed to set the produced condition code to a register CCR1. At the same time, the CCR1 is designated by the subsequent first branching instruction. Then the conditional branching of the process A is executed. Finally the CCR1 storing the condition code of the process B is designated by the 2nd branching instruction. Then the conditional branching corresponding to said condition code is executed.
