Design of embedded network interface controller based on ARM9 and ARMLinux

Abstract

With the development of industrial Ethernet technology, Ethernet has infiltrated into the control layer and equipment layer of control system network. However, a large number of industrial site equipment is not equipped with network interfaces, and they perform communication through serial ports, so they fail to be connected to Ethernet directly. With the development of technology, 32-bit microprocessor has become the mainstream of embedded market application. In the article, the 32-bit microprocessor S3C2410 is chosen to be the embedded interface controller developed as main chip to realize the conversion between serial port data and Ethernet data. Without changing the original equipment, network interface is added so that the conventional serial port equipment can be connected to the Internet through standard TCP/IP protocol. © 2009 Springer Berlin Heidelberg.
