高性能嵌入式终端节能技术研究

摘要

为提高嵌入式终端处理能力,需要使用高性能处理芯片,如此会导致功耗提高.本文在嵌入式终端设备上,以嵌入式Linux操作系统为例,修改启动加载程序Bootloader、Linux内核,实现了动态电源管理技术.通过实验验证,动态电源管理技术在嵌入式终端上的节能效果显著.%In order to improve the processing capability of the embedded terminal, high-performance processing chip is needed, it will cause the improvement of the power consumption.In this paper, embedded Linux operating system is used in embedded terminal and dynamic power management technology is achieved by modification of Bootloader and the linux kernel. Experiments show that dynamic power management technology saving a lot of energy in embedded system.
