面向控制流密集型电路的高层次低功耗方法

High-level low power method for control flow intensive circuit

通过对控制流密集型电路的分析和研究,提出一种面向控制流密集型电路的高层次低功耗综合方法。在调度过程中,应用分支控制和多电压两种方法对设计电路功耗进行双重优化。实验结果表明,在相同的时间和资源约束下,该方法比单独应用分支控制的调度方法功耗平均降低19.04%,比单独应用多电压的调度方法功耗平均降低5.74%。

This paper proposed a high-level low power synthesis method for control flow intensive circuit based on the analysis and study of control flow intensive circuit. The combination of branch control and multiple voltages could be used to realize double-optimization of power consumption of design circuits in the procedure of scheduling. Experimental results show that the combined use of the two methods has reduced power consumption averagely by 19. 04% and 5. 74% ,compar respectively with the separate use of branch control and multiple supply voltages,in the same time and resource constraint.
