摘　　要：从软硬件角度探讨SoC处理器电源管理系统的设计,分析SoC处理器PMU的特征,根据其应用需求讨论有关PMIC的设计问题,包括:电源IC内部结构及选型原则,数字PMIC与传统电源IC相比所做的改进,一种新的电源管理总线——PMBus和一种高度整合的PMIC应用。从嵌入式操作系统的角度分析了动态电源管理系统的设计。This paper studies the power management system design for the System-on-Chip（SoC） processor technology. The characteristic of the processor＇s Power Management Unit（PMU） is analyzed. According to its application demands, it discusses the design problems of Power Management IC（PMIC）, which includes： the interior architecture of the power IC and its selection principle, the improvement of the digital PMIC in contrast with the traditional power IC, the application of a new power management bus called PMBus and a highly integrated PMIC. It analyzes the design of Dynamic Power Management（DPM）, which is a module in the embedded operating system.
