PURPOSE: To provide a system and method for processing operation by which sequential writing back is prevented from giving a large influence to the time at which a processing system completes the execution of an instruction. CONSTITUTION: A plurality of instructions is sequentially dispatched to executing circuits for execution. For each instruction, it is discriminated whether or not an exception is generated by the execution of the instruction. When it is discriminated that no exception is generated by the execution of the instruction and by the preceding instruction of the instruction in the sequence of the instruction, the instruction is completed in response to the discrimination regardless of whether or not the executing circuit completes each instruction for which it is discriminated that no exception occurs. |
