动态电压调节(DVS)被认为是低功耗设计中最有效的一项技术。但在应用动态电压调
节技术的过程中，需要考虑许多细节问题，才能使模型真正接近实际系统，从而在分析中得到较优的结果。本文正是在DVS 中考虑到了电压切换产生的时延和能耗，以一种新的模型来分析功耗、改进算法，最终达到降低功耗的目的。文中提出了分配切换时间间隔的一种依据。

Abstract: It is generally accepted that dynamic voltage scaling (DVS) is one of the most effective techniques in saving energy consumption. But in the process of applying DVS technique, some details must be taken into account so that the model can approach real system and the optimal result can be got in the analysis. This paper presents a new model with taking account of delay and energy dissipation caused by voltage transition to analyze energy consumption and improve algorithm, achieving purpose of minimizing energy consumption at last. The contribution is to proposed criterion of allocating transition interval.
Key words: low-power, DVS, transition interval allocation, embedded system
