摘要

本文提出了一种使用数据缓冲区来平滑请求变化并为电源管理创建长空闲的方法。该方法考虑了缓冲区所消耗的功率，并为缓冲区下溢分配了能量惩罚。我们的方法提供了计算最佳缓冲区大小和缓冲区中存储的数据量的解析公式。我们使用视频预取作为案例研究，MPEG-1视频的功耗节省超过74%，MPEG-2视频的功耗节省超过34%。

Dynamic power management for streaming data

This paper presents a method that uses data buffers to smoothen request variations and to create long idleness for power management. This method considers the power consumed by the buffers and assigns an energy penalty for buffer underflow. Our approach provides analytic formulas for calculating the optimal buffer sizes and the amount of data to store in the buffers. We use video prefetching as a case study and obtain power savings of more than 74% for MPEG-1 and 34% for MPEG-2 videos.
