A Simulation Software Development for Performance Analysis of DVS Algorithm for Low Power Embedded System

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.
