我们提出了一种动态规划技术来解决非流水线和功能流水线数据路径中的多电源电压调度问题。调度问题是指为数据流图中的每个操作分配电源电压电平，以最小化给定计算时间和/或吞吐量约束下的平均能量消耗。该能量模型是准确的，并且考虑了输入模式依赖关系、重新收敛的扇出诱导依赖关系以及电平移位器的能量成本。实验结果表明，在多个标准基准上使用四个电源电压电平，与使用一个固定电源电压电平相比，平均节能53%(计算时间限制为临界路径延迟的1.5倍)。
We present a dynamic programming technique for solving the multiple supply voltage scheduling problem in both non-pipelined and functionally pipelined data-paths. The scheduling problem refers to the assignment of a supply voltage level to each operation in a data ow graph so as to minimize the average energy consumption for given computation time or throughput constraints or both. The energy model is accurate and accounts for the input pattern dependencies, re-convergent fanout induced dependencies, and the energy cost of level shifters. Experimental results show that using four supply voltage levels on a number of standard benchmarks, an average energy saving of 53% (with a computation time constraint of 1.5 times the critical path delay) can be obtained compared to using one fixed supply voltage level.
