摘要
在嵌入式电力终端系统中应用多核处理器,可以显著提升系统性能,同时也带来实时性和能耗增加的问题。针对电力工控终端系统的运行特性,提出一种基于时间触发的多核系统节能调度方法。提出一种智能调度方案,可以保证多核系统的实时性要求;同时采用动态电压及频率调节(DVFS)和动态电源管理(DPM)这2种常用的系统级能源管理技术,可以降低多核处理器的功耗。
The application of multi-core processors in the embedded power terminal system can significantly improve the system performance,whereas will also bring about the increasing of the reaction time and the energy consumption.Aiming at the operating characteristics of the power industrial control terminal system,this paper proposes a time-trigger-based energy-saving scheduling method for multi-core systems.An intelligent scheduling scheme is established to ensure the requirements of real-time performance for multi-core systems.Also,two common system-level energy management technologies,such as the dynamic voltage and frequency regulation(DVFS)and dynamic power management(DPM),are adopted to reduce the power consumption of multi-core processors.
