本文提出了一种资源受限的调度方案和延迟受限的调度方案，最大限度地减少功耗的情况下，当资源工作在多个电压。资源受限的调度通过最大限度地利用在降低的电压下操作的资源来降低功耗，并且同时降低延迟。延迟约束调度方案通过将尽可能多的节点（数据流图的节点）分配给以降低的电压操作的资源来降低功耗。这两种方案都考虑了开关活动对功能单元功耗的影响。此外，这两种方案都使用逻辑来降低电平移位器所消耗的功率。实验结果表明，当工作电压分别为5V和3.3V，或5V、3.3V和2.4V时，所提出的方案能够显著降低功耗。
This paper presents a resource-constrained scheduling scheme and a latency-constrained scheduling scheme that minimize power consumption for the case when the resources operate at multiple voltages. The resource-constrained scheduling reduces the power consumption by maximally utilizing resources operating at reduced voltages and, at the same time, reducing the latency. The latency-constrained scheduling scheme reduces the power consumption by assigning as many nodes (of the data flow graph) as possible to the resources operating at reduced voltages. Both schemes consider the effect of switching activity on the power consumption of the functional units. In addition, both schemes use heuristics to reduce the power consumed by the level shifters. Experiments with HLS benchmark examples show that the proposed schemes achieve significant power reduction when the operating voltages are 5 and 3.3 V or 5, 3.3, and 2.4 V.
