Design and implementation of Ethernet communication interface based on network controller

Abstract

This paper introduces a technology for connecting an embedded device to the Internet with single-chip microprocessor chip STC89C52RC as the core chip .The internal structure and characteristics principles of the network interface chip are described, and the corresponding design of hardware and software programming are discussed. This design system can achieve embedding of network protocol stack and driving functions of the network interface card. Experimental results proved that the system could communicate with a remote machine via Ethernet interface for data transmission and obtain desired results.
