PROBLEM TO BE SOLVED: To prevent from waiting at the time of confirmation request by a CPU for an arithmetic result of a test arithmetic processing.SOLUTION: A multi-core system includes a plurality of CPUs (Central Processing Unit), and the plurality of CPUs execute test arithmetic processing at a predetermined interval and confirm an arithmetic result of the test arithmetic processing with each other. Each of the plurality of CPUs interrupts the present processing and executes confirmation processing for the arithmetic result when receiving a confirmation request for the arithmetic result of the test arithmetic processing from another CPU, and restarts the interrupted processing after completing the confirmation processing for the arithmetic result. |
