PURPOSE:To monitor inter-processor communication even at the time of debugging and real operation by monitoring a system I/O signal. CONSTITUTION:When a system I/O signal is inputted to a system I/O decoder, whether the signal is legal for the system or not is checked. When the signal is legal, a signal corresponding to an interruption signal formed in each board of the system is formed and written in a storage device 4 through a bus switch 6. A CPU 5 sends the information read out from the storage device 4 through the bus switch 6 to a communication port 8 and displays it on an external CRT or the like. In the system for executing inter-processor communication by using the system I/O signal, effective information can be obtained at the time of debugging of an inter-processor communication software, and at the time of real operation, its communication contents can be simply monitored.
