| 摘 要： | 针对以往单纯以DVS算法为中心的动态电源管理架构的不足，提出了一种改进的动态电源管理架构，此架构根据TD—SCDMA无线终端支持3G多媒体业务的特点，站在系统的角度上以策略框架为中心对嵌入式系统的不同组件(如CPU，存储器，外设等)进行行之有效的动态电源管理。通过TD—SCDMA无线终端上的实验表明，采用该架构后，系统平均能耗比没有采用电源管理时下降了50％，大大提升了无线终端的实际应用价值。

| Abstract: | The dynamic power management(DPM) architecture described in this paper can remedy the deficiencies of the previous architectures centered by DVS algorithm . And the architecture centered by policy frameworks effectively manages energy dissipated of different components in embedded system such as CPU,memory,peripherals and so on at the view point of system,which aims at the characteristics of TD-SCDMA UE supporting 3G services. The experiments in TD-SCDMA UE show that the average energy of the system with this architecture is lower 50% than that without it. So the application of this architecture can improve the practical value of the UE. |
