中文摘要：

新一代的智能终端对低功耗、高性能的指标要求越来越高.从终端设备的动态电源管理入手,对基于随机模型的适应性动态电源管理（DPM）算法、CPU使用率和外围电源模块进行分析;依据用户服务质量（Qo S）指标,运用动态电压频率调整（DVFS）经验公式对软硬件进行分析,并结合DPM技术从用户不同的Qo S指标需求对处理器进行调频调压.利用软件对其进行仿真测试,由仿真结果得出智能设备能耗降低的程度.

英文摘要：

Compared with the ordinary equipment, the demands of new generation of intelligent terminal on low power consumption, high performance indicators is higher and higher. From the perspective of the terminal equipment of dynamic power management, the adaptive DPM algorithm based on stochastic model,and power supply module based on CPU utilization and the periphery were analyzed. From quality of service（QoS） parameters for user,analysis was conducted from two aspects of hardware and software on the basis of the experience formula of DVFS, and DPM technology was combined to deal with different QoS requirements from users for FM regulating processor. The simulation test by software shows that the intelligent equipment can reduce energy consumption.
