动态电压频率调节技术(DVFS)是从软件层面进行系统功耗管理的重要技术。本论文针对交互式系统的特点，首先分析了当前使用的 DVFS 策略的不足之处，然后提出并实现了一种适用于交互式系统的 DVFS 策略。该策略在保障用户体验的前提下对移动设备进行功耗优化。实验结果证明，对于大多数应用能达到10%以上的功耗优化效果，部分应用最高有超过30%的功耗降低。

Dynamic voltage and frequency scaling technique (DVFS) has been introduced to manage system power at software level. In this paper, we firstly discussed the disadvantages of commercial CPU frequency governors on interactive systems. Then, we proposed and implemented a new DVFS scheme aimed at Interactive Systems. The scheme is designed to save system power based on the premise that user experience must not be declined. Experimental results demonstrated that most application can save more than ten percent power compared with the original Ondemand DVFS governor, and even more than thirty percent for some other applications.
