嵌入式系统的低功耗调度算法研究

嵌入式系统的低功耗调度算法是嵌入式低功耗技术研究的重要研究方向,文中研究了一种任务间存在依赖关系的嵌入式系统的低功耗调度算法,建立了该低功耗调度算法的数学模型,由于模型的求解复杂性,结合嵌入式系统低功耗调度流程,通过一种比较简单的分步式思想,方便地求解了该低功耗调度算法的数学模型;建立了一个有6个任务的有依赖关系的任务集,通过该调度算法,对该任务集进行了调度,调度后的算法与调度前的算法对比降低的该任务集的能耗;最后用VC编程语言编程仿真验证了该低功耗调度算法的低功耗特性.

Research of Reduction Power Consumption Scheduling Algorithm of Embedded System

The low -power embedded scheduling algorithm is an important research direction of technical research of low-power embedded system. This paper studies a task on the relationship in the low-power embedded system, a low-power scheduling algorithm of mathematical model is built, due to the complexity of the model based on embedded system, low power dispatching flow through a simple,convenient involved, the low consumption of solving mathematical model of scheduling algorithm. Build a six task has dependencies, through the task scheduling algorithm for the tasks set for the scheduling algorithm, scheduling algorithm is compared with the former scheduling of reducing the task set of energy consumption. Finally using VC programming languages simulation system of low power consumption.
