PURPOSE:To increase the number of tasks which can be parallely executed from a memory number for task execution control by interrupting the task at the stable condition time of the task and using the memory for task execution control, which is interrupted, for the execution of the other task. CONSTITUTION:A first storing part A includes a memory 6 for task execution control and an executing part B uses the respective memories for task execution control in the storing part A and executes the multiple execution of the task. A task interrupting detecting means C detects an interrupting request, which is outputted from the task to be executed in the executing part B, and a second storing part D is composed of interrupting time information accumulating memories 7 and 13, etc., to be correspondent to the task. Further, an escaping means E causes task executing information to be allocated to the task, from which the interrupting request is detected by the means C, to escape to the storing part D. Then, a task condition control part F detects a timing in which the task moves to a non-stable condition and issues a restarting request. A restoring means G restores the task executing information to the idle memory for task execution control and instructs task activation. |
