摘要

The task management method, by dividing a unit time of treatment with the non-protected does not guarantee the protection band and the real-time to ensure the real-time zone, when the processor processing capability decreases, the execution of the tasks to be executed in the non-protected areas a skip to the enemy. That is, when a low operating frequency in order to suppress heat generation of a processor, to ensure the real-time instead of the tasks to be executed in the guard band for processing in a port on the tasks to be executed in the non-protected zone at the best. Accordingly, the task management of adequately even if the operating frequency change is carried out fully exhibit the processing power of the processor. ; Task, the control target table, a frequency detector, registration, scheduling unit, the task table, the switching instruction, the task management unit
