可变压处理器上硬实时系统的作业调度

Job Scheduling of Hard Real-Time System on Variable Voltage Processors

在设计实时嵌入式系统时,如果能够善于利用可变电压处理器,可以极大减少系统的能耗。介绍了在动态优先级和静态优先级情况下,确定调度某个给定作业集所需最低电压常量,确定可变电压处理器的最优电压调度方案的思想和算法。

Variable voltage processors, if used properly in designing real-time embedded systems, can dramatically reduce system energy consumption. In this paper, we introduce the ideas and algorithms of determining the minimum constant voltage needed to feasibly schedule the given job set, and the optimal voltage schedule scheme on variable voltage processors, which are suitable for static priority scheduling and dynamic priority scheduling.
