PURPOSE:To shorten the execution processing time of a program by selecting step numbers corresponding to turned-on flags on the basis of contents of a step address storage part and executing the read of only instructions of selected step numbers. CONSTITUTION:All step numbers of the program and addresses of a program storage part 2 where these step numbers are stored are stored in a step address storage part 4. Flags are set in a step flag storage part 6 in accordance with step numbers, and these set flags are stored. A control part 1 turns on or off the flag corresponding to the step number in the step flag storage part 6 in accordance with read, decoding, and execution of each instruction, and a control unit corresponding to the turned-on flag is selected on a basis of stored contents of the step address storage part 4, and only instructions included in this control unit are read out, decoded, and executed. |
