<p>A master CPU makes an execution interval b, during which CPUs are operated, common to CPUs including the master CPU and makes a stop interval a, during which the CPUs are stopped, different for each of the CPUs including the master CPU. As a result, the lengths of cycle intervals c of the CPUs constituted by the execution interval b and the stop interval a allow the ratio between the lengths of the cycle intervals c of any CPUs to be represented by two integers that are coprime to each other. Setting such lengths of the cycle intervals c of the CPUs achieves the synchronism between the shifts of all of the CPUs from a stopped state to an in-operation state and from the in-operation state to the stopped state.</p> |
