摘要
针对Android系统设备电池供电时间及散热受限的问题,提出一种基于任务级调度策略IDSP实现改进动态电源管理框架的电源优化方案.从系统高性能、低功耗出发,引入电源管理扩展框架理论,在基本框架中扩展了CPU负载检测和策略优化两个模块,任务级策略优化过程中,动态调度外设的同时,根据设备约束条件,动态检测并调整CPU工作频率,解决Android系统功耗瓶颈.结果表明:算法在保证系统性能的前提下,能够延长设备使用时间,有效减少系统整体耗能.
For Android system equipment running time and battery power cooling limited,a power optimization scheme based on an on-line device scheduling policy called IDSP （Improved Device Scheduling Policy） is introduced.And it is used to realize improved dynamic power management Architecture; Start with high performance and low power consumption before the expanded frame,including CPU load testing and optimizing strategy two modules.And in the process of optimizing strategy,it can dynamic scheduling peripherals,dynamic test and adjust the CPU work frequency according to equipment constraint conditions as well.The scheme solves the Android system bottleneck power consumption.The experimental results show that the presented method is more promising in equipment utilization and system energy consumption except the system performance.
