An interrupt handler unit () generates a timer interrupt at an interrupt time, and executes an interrupt preparation process. A wait time period measurement unit () a measures a time period from completion of the interrupt preparation process to generation of a start request () as a wait time period. A time calculation unit () calculates a subtraction time period based on the wait time period measured by the wait time period measurement unit (), and calculates a preparation time period that is the sum of a time period obtained by subtracting the subtraction time period from the wait time period and a processing time period of the interrupt preparation process. The time calculation unit () stores a time obtained by shifting back the preparation time period from the time of a next start request (), as a next interrupt time, in a time storage unit ().
