基于任务级的设备动态调度机制的设计与实现

传统动态电源管理（DPM）策略仅仅建立在对目标设备的工作负载进行观测的基础上。由于这些设备级的DPM策略只能隐式认为所有工作负载来自于同一个任务请求源，因而带有一些不可避免的缺陷。在DPM范畴内提出了一种基于任务级的动态功耗降低技术，通过对任务请求源进行划分以及系统级的准确建模，从而能够提供PM更多有关将来的工作负载请求信息。实验结果表明，EODSA策略及其改进策略都具有稳定性，而且在满足相应假设和前提条件下都能够更为显著的降低外设乃至整个系统的平均功耗。

Design and implement of devices' dynamic control mechanism based on mission level

Tactics builds tradition DPM only on the basis of carrying out observations on target device working load. Since these device-level Dynamic Power Management's (DPM) tactics can only implicitly think that all loads come from the same source, some inevitable defects come into being. The main body of main works was suggested that one kind of mission level-based development power dissipation reduces a technology within DPM category, by requesting that the source carries out partition and system level accuracy builds a model to the mission, being able to provide more working load request for information about future of PM thereby. And the experimental result indicates the stability of Energy Optimal Device Scheduling Algorithm (EODSA) tactics brought forward in this paper and their improved tactics. Besides, the average power consumption of accessory devices and even the whole system can be significantly reduced given with the corresponding hypotheses and preconditions.
