摘要

频率电压协同功率控制(FVC)是动态利用软件负载信息的一种有效的降低程序功耗的方法。作者首先通过数学分析表明，只有两个频率电压组的FVC对于电流低vdd的CPU芯片是足够的。实验结果表明，在MPEG-4视频解码器上采用FVC反馈控制可以将解码器功耗降低到1 / 4。

Design rule for frequency-voltage cooperative power control and its application to an MPEG-4 decoder

Frequency-voltage cooperative power control (FVC) is considered a powerful method to reduce the power consumption of a program, because it utilizes the information of software loads dynamically. The authors first show through a mathematical analysis that FVC with only two frequency-voltage sets is sufficient for current low-Vdd CPU chips. Then we show an experimental result that FVC feedback control on an MPEG-4 video decoder can reduce the power to one-fourth.
