Research and Implementation of Embedded Linux System Power Optimization

摘要

This paper firstly discusses the techniques to optimize power consumption of the embedded operating system, and then optimizes power consumption of embedded Linux by adding DVS (dynamic voltage scaling) module and modifies the scheduling function in the standard Linux kernel. Finally, take a comparison test on arm 920 platform. The test results show that: the power optimized Linux can effectively reduce the power consumption of the whole embedded system.
