<p>PROBLEM TO BE SOLVED: To prevent program interference and also to prevent processing having high real time property from delaying in the case of making the same memory area to be an operation object in processing programs having different priorities. SOLUTION: The operation of the memory area to be an operation object for (a) failure detection processing of an A task 61 having a high priority and for (b) failure detection processing of a B task 62 having an intermediate priority is carried out by memory operation processing of a C task 63 having a low priority by issuing events from the (a) and (b) failure detection processing. Namely, the memory area operation is carried out not by the priorities of the (a) and (b) failure detection processing but by the same priority. In the case of the same priority, even though events are issued within a short time from the (a) and (b) failure detection processing, memory operation processing for one event is prevented from interrupting while memory operation processing for the other event is carried out.</p> |
