Design of the Communication Server Based on Embedded Linux and ARM9

With the development of technology, the Embedded System has come to the era of 32-bits. During the period of Late-PC, with the highly development of digital information technology and network technology, the Embedded System has widely immerged into every aspects, such as technology research, engineering design, military tech, kinds of products and commercial art, entertainments and personal life. With the deeper and wider development of world wide embedded products, the embedded technology has become more and more related with people's daily life. This article mainly introduces the hardware-software co-design of Ethernet ,Can and Serial communication system based on ARM9(EP9302) microprocessor and embedded Linux system.
