Task control method and semiconductor integrated circuit

Abstract

A task control method by which when a multiprocessor device having processors executes application software tasks, checkpoints have been buried in the application software tasks in advance. In course of execution of each application software task, the checkpoints are used to make an inquiry about passed one of the checkpoints in the task. Then, the progress of each task is judged based on the current passed checkpoint identified as a result of the inquiry and a passed budget corresponding to the passed checkpoint. Based on a result of the judgment, a resource shared by the tasks is controlled, and a new passed budget is set. Thus, the restriction on the scope of application of an application software program is reduced.
