Energy efficiency is an important property of mobile and pervasive computing devices. Dynamic Voltage Scaling (DVS) is an energy saving technique; achieve this property by reducing energy dissipation of the core by lowering the supply voltage and operating frequency. In this paper, a simulation environment for testing of different DVS algorithms under EDF and RM has been discussed-as there are no standard simulators readily available in market. The simulator environment provides a framework for objective performance evaluations of different DVS algorithms. Several key DVS algorithms recently proposed for hard real-time periodic task sets have been compared; analyzed for their energy efficiency and discussed the performance differences quantitatively.
