基于队列的动态电源管理策略

动态电源管理技术是一项系统级电源优化策略,它通过有选择性的关闭(或者降低性能)空闲的可控设备来降低功耗.在回顾以往系统级动态电源管理策略的基础上,提出了一种基于队列的新型系统级动态电源管理策略,利用队列不但可以提高对于可控模块何时被唤醒时间的预测命中率,并且能够根据不断变化的任务负载情况进行自身的快速调节,以适应不同任务的要求,通过搭建的SkyEye环境进行仿真,结果验证了在性能和节能方面,该方法优于传统方法.

Policy of dynamic power management based on queue

Dynamic power management (DPM) is a system-level power reduction technique that manages available resources by selectively turning off (or reducing the performance of) system components when they are idle. A queue-based system-level DPM policy is proposed based on the study of several approaches to dynamic power management. It not only it improve the hit rate of the time when the modules should be awake, but also adjusts and adapts to the change in workload quickly. Experiments show that this method achieves better performance and energy saving than traditional ones under SkyEye circumstance.
