本文提出了一种整数线性规划（ILP）模型和变电压调度问题的启发式方法。我们提出了可变电压调度技术，这些技术依次考虑单独的时序约束、单独的资源约束以及一起考虑时序和资源约束以进行设计空间探索。实验结果表明，我们的启发式方法在运行时间的一小部分内产生了与 ILP 方法竞争的结果。结果还表明，使用我们的设计空间探索方法可以生成多种设计方案。使用不同的成本/延迟组合，当使用 3.3V 和 5V 混合电源电压时，单个设计中的功耗可能会相差 6 倍之多。
This paper presents an integer linear programming (ILP) model and a heuristic for the variable voltage scheduling problem. We present the variable voltage scheduling techniques that consider in turn timing constraints alone, resource constraints alone, and timing and resource constraints together for design space exploration. Experimental results show that our heuristic produces results competitive with those of the ILP method in a fraction of the run-time. The results also show that a wide range of design alternatives can be generated using our design space exploration method. Using different cost/delay combinations, power consumption in a single design can differ by as much as a factor of 6 when using mixed 3.3V and 5V supply voltages.
