Abstract

Many scheduling algorithms are available for the real -time system, which maintains hard deadline to solve the issues related to the time that is critical for scheduling in real time system and to provide a better system design in real -time system avoiding poor and erroneous choices for scheduling algorithms. The system is based on a real -time deals with the resource to ensure maximum performance and utilization in real -time. Processor availability plays the main role in choosing the best scheduling algorithm for a real -time system. D VFS is being used extensively for the technique of energy management. The aim of DVFS platform is to minimize energy consumption. In this paper, we will give a new algorithm for DVFS and compare the power consumption and deadline miss ratio of other RT-DVF S algorithm with our algorithm. There are many real time dynamic voltage frequency scheduling (DVFS) algorithms. We have analyzed two independent under loaded task -sets for RT -DVFS scheduler algorithm that is Base -EDF and Static -EDF and devise a new DVFS s cheduler algorithm named Frequency Falling EDF. Our devised FF-EDF algorithm is more efficient than Base -EDF algorithm in terms of power consumption. It also gives better performance than static-EDF in terms of future deadline handling. FF -EDF algorithm focuses on dynamic voltage frequency scheduling.
