Analysis and improvement of real-time performance and power dissipation in linux

Linux operating system makes itself occupy an important position more and more in embedded system field because of one's own characteristic. And embedded systems get more and more extensive application in the course of research and design and exploitation to intelligent instrument and apparatus. In porting Linux operating system for a new embedded system which's hardcore is consist of like MIPS32 4K(C)(TM), we have carried on the careful analysis discussion to real-time performance and software consumption of Linux. We present a novel, simple and applicable approach to improves the real-time performance in Linux and some work of reducing Linux systematic consumption is done at the same time.
