Abstract

The invention discloses a power consumption control method and system orienting to an embedded real-time operating system. The method comprises resource allocation prior to task scheduling and task scheduling, wherein the task scheduling comprises the steps of: S1, comparing the priorities of all ready tasks, and selecting the task with the highest priority as a task to be executed; S2, judging whether the task to be executed can be executed by low-power-consumption operations according to task attributes, if so, executing the task according to a low-power-consumption mode, and tracking the actual executing time of the task, and if not, executing the task according to a user setting and tracking the actual executing time of the task; and S3, searching for a compensation time table to compensate for the generated time shift. According to the invention, by utilizing low-power-consumption operations selectively and tracking in real-time and updating the execution time of the task, the power consumption in the process of task scheduling is controlled, energy resources are saved and time precision is also raised.

Description
