Low Power MPEG Video Player Using Dynamic Voltage Scaling
並列摘要
In static voltage mechanism MPEG video player, takes more energy. In our paper dynamic voltage/frequency scaling (DVS) mechanism is implemented and our player scales the voltage level for the frames of next interval based on decoding time prediction. The decoding time of a frame is predicted by the size and the type of the frame. We implemented our mechanism by modifying a traditional MPEG1 decoder. Our experiments show that a significant amount of processor energy savings can be achieved while enhancing QoS of video playback.
