S3C2410X以太网接口研究与设计

Research and Design on S3C2410X Ethernet Interface

根据以太网网络信息采集的需要,采用以太网芯片CS8900设计了S3C2410以太网接口。本文研究了以太网接口原理,并结合芯片CS8900详细分析了以太网接口数据收发过程。介绍了与设计相关的控制寄存器和引脚,给出了CS8900A与S3C2410X连接的硬件电路连接图。最后在启动代码U-Boot下实现了以太网接口的初始化。嵌入式开发人员可以根据开发需要借鉴本文的设计思路设计其他的以太网接口。

For the requirement of the Ethernet data collecting, S3C2410 Ethernet interface using chip CS8900A is proposed. This paper analyze the standard of Ethernet interface and analyze the data receiving and sending procedure combining chip CS8900A. Here I introduce some register and pins related to the design ,and give the figure of the hardware S3C2410X and CS8900A connection. At last, using U-BOOT realize the initialization to Ethernet interface. Development designers of embedded system can use this train of thought to design other Ethernet interface.
