摘要
文章提出了一种基于模式切换的调频DPM(即动态电源管理)的方法,它能根据CPU运行的负载情况,在预先定义的运行模式之间进行切换以调整CPU的工作频率,从而进一步降低系统的功耗,达到增加电池使用时间和延长设备使用寿命的目的。
This paper proposes a DPM approach based on mode switching. According to CPU running workload, it can switch CPU among certain predefined running modes so as to adjust the working frequency of CPU, therefore system power consumption can be decreased further in order to increase the battery duration and extend the device lifetime.
