基于访存特性的嵌入式移动设备软件低功耗优化方法
Embedded and mobile device software low-power optimization methods based on storage system’s accessing characteristics
摘要
Abstract
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.关键词
