摘　　要：针对嵌入式系统的低功耗设计,提出一种面向对象的软件电源管理模型。在操作系统的基础上将相关API封装与扩展,抽象出操作系统电源管理类(OSPM)、CPU电源管理类(CPUPM)、设备驱动电源管理类(DDPM)、应用程序电源管理类(APM)。在操作系统层、驱动程序层、应用程序层之间形成电源管理接口,简化嵌入式系统电源管理的软件设计与维护。Aiming at low power consumption design of embedded system, a software power management model is put forward, which based on object-oriented principle. On the foundation of operating system, the related APIs are packed and expended. In the mean time, four classes are abstracted which are Operating System Power Management class（OSPM）, CPU Power Management（CPUPM） class, Device Driver Power Management（DDPM） class and Application Power Management（APM） class. Within operating system level, device driver level, application level, and the power management interface are formed which make the software of power management easy to design and defend for embedded system.
