Abstract :
Dynamic voltage and frequency scaling (DVFS) is one of the popular energy conservation techniques for battery operated real-time and embedded systems. This paper presents EEDVFS, an energy efficient DVFS scheduling algorithm for mixed task set. EEDVFS is a variant of Earliest Deadline First (EDF) based Deferrable Server (DS). Experimental results show that EEDVFS reduces energy consumption without compromising on periodic task deadlines and aperiodic task responsiveness. The results of EEDVFS are compared with non-DVFS EDF version of DS upon various performance metrics such as energy consumption, average response time, latency, preemption count and number of decision points. EEDVFS offers 54% energy saving in comparison with the non-DVFS EDF based DS algorithm.
