Abstract: A high-level low power scheduling method for multiple supply voltages is proposed,which is constrained under time and resource.By means of Lagrange multiplier method,this method distributes the slack to the operator nodes in the data path,thus,efficiently reduces the energy consumption of design circuit.In the process of scheduling and adjusting,the operator nodes both in critical path and non-critical path can be dealt simultaneously.The feasibility of this method for power optimization is demonstrated by experimental results.

摘要: 提出了一种在时间和资源约束下的高层次多电压低功耗调度方法。应用拉格朗日乘数法,将空闲时间分布到数据通路的各个操作节点上,从而有效地降低了设计电路的能耗。该方法在调度和调整过程中,可以同时处理关键通路和非关键通路上的节点。实验结果表明了该方法在功耗优化方面的有效性。
