PURPOSE:To provide a device by which the change of the program of a subprocessor can be easily performed and error recovery can be performed as an information processor capable of saving power consumption and comprised of multiprocessors. CONSTITUTION:This processor is the information processor of multiprocessor system comprised of a main processor part 1, a subprocessor part 2, and a power source part 3, and a power source is always supplied to the subprocessor part 2 from a backup power source 32. An error notifying means 24 is provided at the subprocessor part 2, and when an error is detected in the subprocessor part 2, the occcurrence of the error in the subprocessor part 2 is displayed, and a main power source 31 is supplied to the subprocessor part 2 via a power source control interface 25 and a main power source control circuit 33, and the main processor part 1 checks a content displayed by the error notifying means 24 after performing start-up processing, and reads out the control program of the subprocessor from external storage 4 when detecting the occurrence of the error in the subprocessor part 2, and loads it on the memory 22 of the subprocessor 2 via an inter-processor communication means 26. |
