Research of migrating Linux to embedded systems and analysis of real-time performance of embedded Linux

At present, the embedded systems are becoming more and more popular for their portable and multi-functional properties. They are used in many domains and located ubiquitous. In this paper, we describe a framework for migration from normal Linux platforms to embedded Linux systems. By the detailed analysis of current real-time performance and process management methods in normal Linux, we reformed its scheduling mechanisms and provided a new approach to promote its performance in the real-time application environment of embedded Linux system. At the end, several experiments are made to explain the reforming methods of the process scheduling mechanism of Linux, and the effectiveness and efficiency of our approach are demonstrated.
