Abstract: Dynamic power management is emerging as a technique for meeting stringent power and performance requirements of the portable system by changing processor speed and voltage at run-time depending on the need of the applications running. This article introduces a scheme relating to dynamic power management for embedded system, and reveals particularly two crucial problems in this scheme: how to detect dynamically and how to expand the detecting data from processor.

摘要： 动态电源管理旨在根据当前应用的需要来调节处理器电压和频率从而满足便携式系统的高性能低功耗的要求。该文介绍了一个嵌入 式系统动态电源管理方案。阐述了动态探测问题以及怎样对基于处理器的探测数据进行扩展。
