PROBLEM TO BE SOLVED: To reduce the load of timer resetting processing due to an interval timer interrupt event by providing a timer designation table having information showing a timer counter performing updation next. SOLUTION: A timer processing means 102 is used at the time of performing processing execution of an interval timer interrupt event 113. The timer processing means 102 consists of a timer selecting means which selects a timer to be processed in interval timer interrupt processing, plural timers which decrement timer values corresponding to respective timers in every processing and a timer designation table 103 which designates a timer to be next processed. The table 103 generates a cyclic integer (i) for dispatch processing. When an interval timer interrupt occurs, the main processing part of this system enters timer interrupt processing and the processing of only one timer selected according to the integer (i) is performed.
