基于S3C44B0的以太网驱动程序设计与实现

Ethernet driver design and implementation based on S3C44B0

为实现嵌入式系统的以太网通信接口驱动程序,就S3C44B0开发板的以太网接口芯片RTL8019AS的驱动程序设计,来系统地分析以太网控制器和物理层芯片的驱动程序设计原理和实现方法,完成了芯片的初始化,以及实现数据的收发功能,并在开发板上进行了功能测试。从而增强了网络的智能化与灵活性,提高了其安全性和实时性。

In order to achieve the Ethernet Driver program of the Embedded System,this article debates the design of the drive program of ethernet connection chip RTLS019AS which based on S3C44B0 board,and analyzes the ethernet controller and the physical level chip driver principle of designation and the realization method systematically, then completes the initialization of the chip and the collection function of the data, at last takes a functional board test on the development board. Thus it increases the flexibility and intelligence of the network. So we can enhance the security and timely consideration.
