<p>PURPOSE:To shorten the time of timer control even when a time-out table becomes large by providing an attribute table which contains attributes showing actuation states of application programs and a management table which contains events of forward retrieval and events of backward retrieval. CONSTITUTION:The time-out table 6a has the attribute table 14 containing timer values 71 from a timer control processing means 43a, event IDs 83, and attributes indicating the start states of the application programs 8 and the management table 15 containing event IDs 83 from the timer control processing means 4a, event IDs 83 of forward retrieval, and event IDs 83 of backward retrieval. And, the timer control processing means 4a receives a timer counter signal 31 from an interruption processing means 3, retrieves the event IDs 83 stored in the attribute table 14 associatively when the value is equal and an attribute is being actuated, and outputs time-out information 51 including the timer value 71 to an application program 8.</p> |
