近几年，嵌入式系统产品日臻完善，并在全世界各行业得到广泛应用。嵌入式系统产品的研制和应用已经成为我国信息化带动工业化、工业化促进信息化发展的新的国民经济增长点。消费家电的智能化，嵌入式更显重要Abstract

In recent years, as embedded systems continuing to improve, it widely used in the industry around the world. Embedded systems product development and application have promoted the development of information technology and industrialization. It is becoming a new growth point of the national economy. Moreover, as the home appliances becoming more intelligent, the embedded technology is more important now. The purpose of this project is to build up a highly efficient and stable platform for embedded systems in this environment.

Embedded LINUX has a free and open source characteristics like Linux and gets the strong technical support from linux learners around the world. So Embedded LINUX is a natural choice to embedded operating systems.And the hardware architecture is the ARM architecture.ARM processor type is popular in embedded systems processor type, and the Samsung's S3C2410 and S3C2440 processor, is currently the most popular type of ARM9 processor.

The project is to study how the embedded LINUX kernel and the root file system ported to the embedded target board based on S3C2440 processor system .
