動態(tài)電壓調(diào)節(jié)(DVS)被認(rèn)為是低功耗設(shè)計中最有效的一項技術(shù)。但在應(yīng)用動態(tài)電壓調(diào)
節(jié)技術(shù)的過程中，需要考慮許多細(xì)節(jié)問題，才能使模型真正接近實際系統(tǒng)，從而在分析中得到較優(yōu)的結(jié)果。本文正是在DVS 中考慮到了電壓切換產(chǎn)生的時延和能耗，以一種新的模型來分析功耗、改進(jìn)算法，最終達(dá)到降低功耗的目的。文中提出了分配切換時間間隔的一種依據(jù)。

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.
