Real-Time Task Schedulers for a High-Performance Multi-Core System

摘要

This paper proposes a multi-objective task scheduling algorithm for high performance real-time computing systems designed by the Multicore processor. Most real-time systems are battery powered and operate many complex mechanisms. In such a system, it is necessary to consider the energy consumption, core/processor utilization and deadlock miss rate to improve performance. In order to achieve high efficiency and low power consumption, a multi-objective real-time task scheduler is proposed considering voltage transaction delay, core utilization, unused cores and static and dynamic connection power. Single Objective Genetic Algorithm (GA) and Cellular GA (CGA) are implemented to compare the results with existing methods. The simulation results show that our approach improves performance relatively. Core utilisation is increases from about 5 to 7%. Moreover, the average power consumption decrease is about 12% compared to the existing proposed planners.
