ENERGY-EFFICIENT REAL-TIME TASK SCHEDULER

摘要

An energy efficient task scheduler for use with a processor that provides multiple reduced energy use modes. In one embodiment, a system for executing tasks includes a processor and a task scheduler. The processor provides a plurality of different reduced energy use modes. The task scheduler is executable by the processor to schedule execution a plurality of sleep tasks. Each of the sleep tasks corresponds to a different one of the reduced energy use modes. The task scheduler is executable by the processor to execute each of the sleep tasks, and as part of the execution of the sleep task to: place the processor in the reduced energy use mode corresponding to the sleep task, and exit the corresponding reduced energy use mode at suspension of the sleep task.

主权项

1. A non-transitory computer-readable medium encoded with instructions that when executed cause a processor to:
execute a plurality of sleep tasks, each of the sleep tasks corresponding to a different reduced energy use mode of the processor; and while executing each of the sleep tasks, place the processor in the reduced energy use mode corresponding to the sleep task, and exit the corresponding reduced energy use mode at suspension of the sleep task.
