PURPOSE:To reduce a load for monitoring the inside operating state of the main processor of an information processor, and improve the operating efficiency of the information processor. CONSTITUTION:A subprocessor 1 outputs a search signal to an information sense part 4 by a monitor start signal outputted by a timer 3 in a preliminarily decided time interval. The information sense part 4 reads out a state restoring the state of the intermediate stage of an information processing at a preliminarily decided storage place, stored in an RAM part 71 of a main memory 7 of a main processor 2, at the time of receiving the search signal, compares the state with a preliminarily decided reference, and outputs an abnormal signal to a the subprocessor 1 when this reference value is different from the above mentioned intermediate state. The subprocessor 1 outputs an interruption control signal to a priority informing part 5 at the time of receiving the abnormal signal. The priority informing part 5 outputs a nonmaskable interruption signal to the main processor 2 so that the operation of the main processor 2 can be switched to the operation by a restoration program. |
