Dynamic leakage aware power management with procrastination method

Abstract

Power management is an important factor during the design of real-time systems. Dynamic voltage scaling is an effective technique to reduce dynamic power consumption. With the higher density of processors, the leakage power consumption can not be ignored, which makes power management more complicated. Power shutdown and procrastination method can be used to reduce static power consumption due to leakage current efficiently. A dynamic leakage aware power management algorithm with procrastination for job-level periodic task set using EDF policy is developed. Experimental results show that it derives a good energy performance.
