This paper analyzes the dynamic voltage scaling prediction algorithm,a Dynamic Voltage Scaling(DVS) prediction algorithm based on Cycle Mode Matching(CMM) is proposed to improve the accuracy of DVS prediction.Simulation result shows that,to different test sets,the accuracy of DVS prediction is improved from 4% to 15% using CMM without the perceptible impact of system performance.
