Design Of An Embedded Lab Gateway Based On ARM

Gateway is a device which generates with the development of the Internet. As the Internet's widespread, it brings a question: the IP address is not enough. So the people begin to research and design some devices, which can make a large of computers access to the Internet using only one IP address. The gateway is one of the devices.An independent computer is common used as the local network's gateway in schools and labs, which wastes the resources. This dissertation provides a design scheme for embedded lab gateway based on S3C4510B and uCLinux operating system. And this system has some differences, such as low price, high performance and so on.This dissertation chooses S3C4510B as embedded processor and uClinux as embedded operating system. In the design of the hardware and software of this system, the design of two Ethernet network cards is the innovative and pinch point. At first, it introduces the related knowledge of embedded gateway system and ARM architecture. Then, it introduces in detail the hardware design of this system. And then it generalizes the based knowledge of uClinux operating system, and mainly discuss the how to port uClinux to this embedded system, including how to modify, cut and complicate kernel, how to program the bootloader, how to program device drivers and so on. At last, this thesis provides the solution of lab gateway based on this system and the results.
