PURPOSE:To obtain an artificial input/output device for simulating many kinds of input/output control devices without providing an exclusive circuit, so as to correspond to the input/output control device to be simulated, by replacing a microprogram by one set of artificial input/output control device. CONSTITUTION:A microprogram corresponding to an input/output control device to be simulated is stored in advance in a floppy disk 7. By a microprocessor 5, the microprogram corresponding to the input/output control device to be simulated is stored in a control storage part 1. Subsequently, the program in the storage part 1 is read out and executed under the control of a transfer control part 2, and an interface operation as an artificial input/output control device is executed. Also, several kinds of interface operations can be executed continuously by controlling (8) the transfer control part 2 by the microprocessor 5. |
