Despite recent advances, battery life continues to be a limiting factor in mobile multimedia systems. Significant energy savings can be achieved by adapting systems at runtime to match the execution requirements of different tasks. This paper introduces an on-line dynamic voltage/frequency scaling (DVS) feedback technique that reduces voltage and frequency to match the playback rate. A PI controller adjusts the decoder’s speed to keep constant the occupancy of the buffer between the decoder and… CONTINUE READING
