Integrating operation scheduling and binding for functional unit power-gating in high-level synthesis

Nan Wang, Song Chen, Zhiyuan Ma, Xiaofeng Ling, Yu Zhu

Abstract: Highlights•The leakage energy of functional units is optimized during scheduling and binding.•Leakage energy reduction problem is modified as an idle interval partition problem.•Leakage energy reduction in each idle interval is well estimated during scheduling.•Total leakage energy reduction is evaluated by a min-cost max-flow-based method.•Functional units are clustered to meet the power-domain constraints.
