摘要
叙述了一种以嵌入式Linux为操作系统的智能手机电源管理方案的设计原则、设计框架和实现要点。该方案在嵌入式Linux的基础上,针对智能手机软件环境复杂、对电源持续工作要求高的特点,设计和实现了从内核支持到应用程序的完整的电源管理软件框架。该方案与嵌入式图形运行环境的结合,使得电源管理的状态更容易监测、行为更容易控制;对硬件设计的讨论则体现了软硬件协同设计的思想。
The design principle,the framework and the key points for implementation of a power management software for Linux-based smartphone are presented. A whole framework from kernel to application programs is designed and implemented to meet the special requirements of smartphone in software environment and power consumption. With the combinition of embedded graphics platform, the power status is easier to surveil. The discussion on hardware design embodies the hardware software co-design idea.
