摘　　要：以精简指令集(RISC)技术的S3C44B0X微处理器和RTL8019AS以太网接口控制器为硬件平台,针对嵌入式系统资源有限的特点,文中提出了一种通用的嵌入式系统以太网接口设计与实现方案。首先,对以太网技术进行简单的说明;其次阐述了嵌入式以太网控制器的硬件设计及硬件中各个模块的功能和工作原理;最后给出嵌入式以太网控制器的软件设计过程:介绍引导程序Bootloader的启动过程、建立μCLinux操作系统的开发环境和实现以太网控制器模块驱动程序。The design and implementation scheme of a Ethernet interface for embedded system is proposed, which is based on S3C44BOX single chip computer that uses RISC technology and RTL8019AS network interface controller hardware platform. First, the structure characters of network interface technology are described; then the network interface hardware design and module function and principle is discussed. Finally, the process for design of network interface software is given, such as Bootloader migration, establishment of μ CLinux operating system, and accomplishment of network interface module drivers.
