PURPOSE:To prevent the generation of an incorrect block, by making an information processing system respond to a monitoring processor when the processor informs of a reset request, an executing processor judges a specific internal condition in response to the information and informs of reset approval, and executes the reset. CONSTITUTION:When the reset start button 220 of a monitoring processor SVP 2 is depressed, its information is supplied to a processor section 21. Then a system reset request command is sent to an input-output controlling processor IOP 1-2 which is an executing processor 1, etc. This command is decoded as a reset request RSTRQ at the inside. Upong receiving the RSTRQ, a processor section 11 stops its internal program after waiting the termination of the writing operation of a device, when the device makes the writing operation. By receiving the response of a state read command, the SVP2 judges the stoppage of the microprogram. When stoppage of all parts is judged, a system reset signal is sent and supplied to the resetting circuit of each executing processor 1, and thus, the reset of the system is performed. |
