TASK MANAGEMENT METHOD, TASK MANAGEMENT DEVICE, SEMICONDUCTOR INTEGRATED CIRCUIT, ELECTRONIC DEVICE, AND TASK MANAGEMENT SYSTEM

摘要

This task management method includes dividing a unit time of processing into a reserved band for guaranteeing real-timeness and a non-reserved band not for guaranteeing real-timeness, and skipping a task to be executed in the non-reserved band as appropriate when processor(100) throughput falls. That is, when the operating frequency of the processor(100) is lowered in order to suppress heat generation, the real-timeness of tasks to be executed in the reserved band is guaranteed at the expense of processing the task to be executed in the non-reserved band in a best-efforts fashion. This allows appropriate task management even with variations in the operating frequency, thereby making full use of the processor throughput.
