为了使嵌入式移动产品更加节能环保，提出可通过调整程序中的循环结构和提高程序局部性来优化设备的访存操作，以此减小存储系统和嵌入式设备的功耗。将该方法应用于本实验室研制的麻醉术中呼吸音动态分析与呼吸功能监测系统，并在能耗模拟器HMSim上进行了四组仿真实验，结果显示，各组实验的功耗均有不同程度的降低，按等效方法计算，降幅最大可以达到25．84％。由此可见，所述的方法对于降低设备功耗是可行和有效的。

In order to make embedded and mobile products become more energy-efficient and more environmentally friendly, this paper proposed that adjusting loop structure in program and enhancing program locality could optimize device’s memory-accessing operation,accordingly decreased storage system’s and embedded deviced’s power dissipation.These methods were applied to the breathing sounds dynamic analysis and respiratory function monitoring system in anesthesia surgery developed by the laboratory,then on the energy consumption simulator HMSim,four groups of experiments were made.The results show that every group’s power consumption decreases in different degree.According to the calculation of equivalent method,the largest ratio of energy saving can achieve up to 25 .84%.All these indicate that the methods described by this paper are feasible and effective for reducing device’s power consumption.
