摘要
介绍了一种简单而有效的动态电压缩放(DVS)来降低CPU功耗,同时满足控制需求.针对典型功耗负载变化的两种来源,将时间触发和事件触发两机制进行有机融合,并通过仿真实验来突出该方法的优点.实验结果表明,与传统的DVS方式相比,在保证相当控制性能的条件下,新方法能节约相当的能耗.
The reduction of the energy consumption for the power-constrained microcontroller has become increasingly important, which is, however, generally contradictory to the enhancement of its control performance. Under the condition of meeting the demand on the performance, a simple and effective dynamic voltage scaling （DVS） method is introduced to reduce the CPU power consumption. In respect to the two typical sources of power consumption variation, the DVS method effectively integrates the time trigger mechanism and the incident trigger mechanism. The advantage of the method is highlighted through simulated experiments and results show that, compared to DVS methods, the new DVS method can effectively reduce energy consumption while sustaining performance.
