A Research On Linux Operation System Apply For The Embedding Device

With the development of Computer technology and Communication technology in Information times and the board application of Internet, it is clear that 3C (Computer, Communication and Consumer) will converge in the near future which will lead the focus of Computer Industry from the Compute product to Information product. It is the concept of Information Appliance. In the application and development field of Information Appliance, Embedded Operating System will be the most favorite thing in Software Development field. At the same time, in the field of computer science itself, the micromation and specialization is the new direction of the computer world. It also want the support of Embedded System. So, the research of the key technique of embedded system——Embedded Operating System is the most important thing.This thesis presents the author's work in research of the Linux-based Embedded Operating System for his bachelor degree. Most of the thesis focus the requirement of transforming Linux to Embedded System. Firstly, it describes the concepts of embedded system and Information Appliance, and presents the characteristic and development environment of Linux. Then describe three aspects of the key techniques of using Linux as the development tools of Embedded system Including the real-time variant of Linux——RT Linux and it's principle, implementation and the programming; the network coding in Linux kernel and the analysis of Linux network device drivers and the online debug environment of Linux Kernel and RTLinux Kernel. I have also involved the implementation of embed Linux/RTLinux in a floppy to simulate the embedded environment. In the last part of this thesis, I give the suggestions and prospect of the development of a mature embedded system which have the most competition ability in China market base on the current work.
