【摘要】 对于嵌入式系统来说,硬件选型一旦确定,系统的功耗就取决于软件设计,而操作系统是实现低功耗设计的最合适的一层。通过对目前嵌入式Linux系统的主流的功耗优化技术包括动态电源管理技术(DPM)、动态电压调节技术(DVS)及其他的一些功耗调度算法进行详细的介绍,分析各技术的特点,并在此基础上提出了嵌入式Linux系统功耗优化的新思路。更多还原

【Abstract】 For embedded systems,once the hardware selection is determined,the power consumption depends on software design,and the operating system is the most suitable level to achieve low-power design.The paper described the main embedded Linux system power optimization techniques,including dynamic power management(DPM),dynamic voltage scaling(DVS) and some other power scheduling algorithms,the analysis of their characteristics was given,and based on this we proposed some new ideas for embedded Linux system power optimization.更多还原
