A CPU #0 detects an assignment instruction for a process 1. The CPU #0 acquires a remaining time obtained by subtracting a CP of a handler B (processing time of handler A) from a period (Dt of handler B) that is from the time when an event of the handler B occurs, which is interrupt processing assigned to a CPU #1. The CPU #0 judges if the acquired remaining time is greater than or equal to a processing time (CP of process 1) defined to limit an interrupt in the process. In other words, when the process 1 is assigned to the CPU #1, even if an event of the handler B occurs during execution of the process 1, the CPU #0 judges whether the Dt of the handler B can be met. When the event of the handler B occurs during execution of the process 1, the CPU #0 judges that the Dt of the handler B can be met and therefore, the CPU #0 assigns the process 1 to the CPU #1.
