摘　　要：随着网络技术的迅速发展,嵌入式系统也向着网络化的方向发展。而以太网的广泛使用,使得嵌入式技术与以太网结合就成为一个新的发展研究方向。系统采用三星S3C2440嵌入式微处理器,CS8900A以太网控制芯片,分析了以太网芯片软件设计的主要步骤,重点分析其原理及实现过程,最后将驱动程序采用静态编译的方式编译进内核,至此完成了在Linux操作系统下以太网的驱动开发。实现了嵌入式设备更高可靠性以及更快速度的通讯方式,提高了嵌入式系统的整体性能。Along with the rapid development of network technology, embedded system is developing toward the direction of network. While Ethernet is widely used, embedded technology and Ethernet combination became a new development direction of research. The system adopts the Samsung S3C2440 embedded microprocessor,Ethernet control chip using CS8900A,analyses the main steps of the Ethernet chip software design, focuses on the analysis of its principle and realization process. Finally the driver compiled into the kernel with a static way, this completed the Ethernet driver development in Linux operating system. Realize higher reliability and faster means of communication in embedded equipment, improve the overall performance of the embedded system.
