Abstract

Minimization of energy consumption in the battery operated system is become a major issue. Most of the real-time systems consist of a battery operated microprocessor system with a limited battery life. So, energy consumption is becoming a critical issue in the design of embedded systems because of the popularity of portable devices such as mobile devices and personal digital assistants. In this paper we propose a approach to handle task synchronization for Real Time Systems with energy efficiency consideration. Our p r o p o s e d approach is a variation of the well known priority c e i l i n g protocol (PCP) which is to enforce mutually exclusive a c c e s s to shared resources. W e a r e using the concept of speed locking i n p r o p o s e d a p p r o a c h s o t h a t we can save the enrgy consumption.
