摘要
在嵌入式计算领域,随着多核处理器的应用发展,能耗问题越来越被重视。目前针对多核系统的应用,基于动态电压频率调节(DVFS)的实时节能调度技术研究较多。介绍了多核系统节能调度技术的发展,重点讨论了并行任务模型技术,介绍了重定时有向无环图模型的优势,并提出了一种基于DVFS的多核节能调度算法流程,为促进多核处理器系统在实时嵌入式领域的应用提供了理论和技术参考。
With the application of multi-core processors,energy consumption is now of primary consideration in the real time embedded areas. As to the applications for multi-core systems,a scheduling technology based on dynamic voltage frequency scaling( DVFS) is studied more. This paper introduces the development of energy-efficient scheduling in multi-core systems,discusses the technology of parallel task model,introduces the advantage of re-timing directed acyclic graph model. An algorithm flow of energyefficient scheduling based on DVFS is proposed in multi-core systems. It provides an theoretical and technical reference for the application of multi-core systems to real-time embedded field.
