PROBLEM TO BE SOLVED: To solve a problem that there is the possibility of runaway of a sub- processor which seriously damages a system, when a starting program of the sub-processor stored in a memory for the sub-processor is lost, in a conventional multiprocessor system provided with a main processor, the sub-processor, and a non-volatile rewritable memory for the sub-processor, storing the starting program and the like used by the sub-processor. SOLUTION: The main processor is started prior to the sub-processor, and the starting program of the sub-processor is written in the memory for the sub-processor according to the necessity within a predetermined time before the start of the sub-processor, whereby the runaway of the sub-processor can be prevented. |
