Abstract

This paper demonstrates simulation Events, a model based design and simulation tool and its application in assisting a design concept of fair scheduling along with governing in embedded system. The process of implementing the scheduling in real time systems have to satisfy the deadline constraints with maximum jobs to be scheduled and besides, the energy efficiency of the processor is to be increased. In this paper, a Dynamic Voltage Scaling (DVS) controller is modelled for energy efficient scheduling subject to meet real time processing constraints. The authors have designed a model to improve the efficiency of the system by raising the probability of entities to meet their deadlines respectively. The design of system based on DVS is mainly aimed to reduce the voltage taken by the processor and also the scheduling of entities using scheduled time out block which is used to achieve energy efficiency and also calculate the residual time taken by the entities. The comparison of results is done which shows the reduction in voltage of the processor. These proposed designs can achieve significant energy gains along with improving the quality of user experience also.
