Multi-core processor including a monitored processor core whose process result is to be monitored by a number of processors based on processing load

Abstract

A multi-core processor includes a monitored processor core whose process result is to be monitored; a monitoring processor core group including two or more monitoring processors which can perform a process for monitoring the monitored processor core; an evaluating part configured to evaluate a processing load of the monitoring processor core group; and a controlling part configured to make the monitoring processor core group perform the process for monitoring the monitored processor core in a distributed manner if the processing load of the monitoring processor core group evaluated by the evaluating part is low, and make the monitoring processor of the monitoring processor core group perform the process for monitoring the monitored processor core if the processing load of the monitoring processor core group evaluated by the evaluating part is high, the monitoring processor performing a process whose priority is relatively low.
