摘要
嵌入式多处理器系统中的能耗问题是一个重要的研究方向。在研究单处理器动态电压缩放和多处理器的PF调度算法的基础上,提出了一种多处理器节能调度算法。该算法针对周期任务,通过静态分析确定最低处理器调度要求,在满足可调度性的条件下动态缩放各个处理器电压,从而有效地降低了整个系统的功能。
In order to improve the computing capability of embedded system, saving energy in multiprocessor systems is an important issue. In this paper, a scheduling algorithm is proposed for the multiprocessors based on dynamic voltage scaling algorithm and PF algorithm. By applying this algorithm, the energy for periodic tasks can be saved effectively and meet the dynamic voltage scaling in schedulable conditions.
