摘　　要：嵌入式系统的DPM问题就是通过在系统的部分组件空闲时关断其电源,并在有任务到来时恢复对它的供电,以减少系统级功率消耗,其目的就是在最小系统功耗的情况下实现最优的性能。要实现此目的,迫切需要有一个高性能的电源管理算法。该文研究了目前国际上比较流行的几种系统级动态电源管理算法,比较并指出各个算法的优缺点及改进的方法,为发展高性能的智能电源管理算法提供理论分析和实验比较结果。The problem of power management for an embedded system is to reduce system level power dissipation by shutting off parts of the system when they are not being used and turning them back on when requests have to be serviced.The goal is to give high performance with the most small power dissipation.A computable-evolvable intelligent power management algorithm is urgently needed.In this paper,we survey several approaches to system-level dynamic power management .We describe how the use of the DPM algorithms can impact the overall power dissipation,and show how to improve the performance of them.
