Abstract
A failure diagnostic system (100) for a multicore CPU having installed therein a plurality of CPU cores (11) that is configured to be switched from a SMP mode to an AMP mode includes: load prediction means for predicting a processing load of the multicore CPU; mode switching means for switching at least one of the CPU cores (11) to the AMP mode when the processing load is less than a threshold; and failure diagnostic means for performing a failure diagnosis of the CPU core that has been switched to the AMP mode.
