117 Task Scheduling in Multi core Embedded Real time System to Improve Energy Consumption and Efficiency Hossein Mahmoudi Hossein mahmoudi@ec iut ac ir Department of Electrical and Computer Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language Farsi Supervisor Dr Mohammad Ali Montazeri Montazeri @cc iut ac ir Abstract Today as a result of electronic business development and controlling facility requirements embedded system importance and applications increased as it became one of the most important research areas in computer science in recent years In most of the times embedded systems operations should be done before hitting a specific deadline so almost all of embedded systems are real time Military and industrial equipment cellphone and other commercial applications like ATM and intelligent systems are samples of these systems In addition to real time feature low energy consumption is another main feature of embedded system which is a main issue for digital system designers Task scheduling and executing on present cores is the key problem in multi core systems In contrast to single core that scheduling only defined as a matter of time in multi core systems the scheduling problem is a two dimensional issue because the execution space comes into consideration in addition of time It means that we should decide when and where a task should execute to achieve processing power performance and execution time efficiency Here we focus on four aspects of these types of systems energy consumption system efficiency system performance and system response time Load distribution pattern on available resources multi core processors affects all of the above
