Abstract
In a multiprocessor system having a high-performance processor and a low-power-consumption processor, tasks are properly assigned to the high-performance processor or to the low-power-consumption processor even if the tasks include those commonly used by a plurality of applications. The applications each include a plurality of tasks that are driven by an input or sequentially driven by another task. A task scheduler mechanism includes a synchronization mechanism that causes a driven task to inherit a priority assigned to the input or a synchronizing task, and a task assignment mechanism that determines in accordance with the inherited priority whether to assign the driven task to the high-performance processor or to the low-power-consumption processor.
