高层次综合(HLS)技术的核心是数据通路的调度和分配问题,而操作调度是HLS中最重要的任务,它决定了数字系统处理速度与硬件费用之间的折衷。本文主要研究的是调度中的算法,在高层次综合中基于传统的力驱动布局算法提出了一种新流程的力驱动调度算法,并把此算法应用到解决功耗的问题中。与经典力驱动调度算法相比较,该算法在降低功耗和时延方面取得了更好的效果。
At the heart of high-level synthesis (HLS) technology is the scheduling and allocation of data paths. Operational scheduling is the most important task in HLS, and it determines the trade-off between digital system processing speed and hardware costs. In this paper, we mainly study the algorithms in scheduling. Based on the traditional force-driven layout algorithm in high-level synthesis, a new force-driven scheduling algorithm is proposed and applied to solve the problem of power consumption. Compared with the classical power-driven scheduling algorithm, this algorithm has achieved better results in reducing power consumption and delay.
