基于ARM和DM9000的网卡接口设计与实现

Design & Realization of Embedded Ethernet Interface Based on ARM and DM9000

针对ARM CPU S3C2410的特点,设计开发了外围网卡接口平台,通过驱动程序对以太网控制芯片DM9000的控制,实现了网络数据传输功能。硬件方面主要涉及以太网网络接口的设计,软件方面主要是设计以太网控制芯片驱动程序。该嵌入式系统网络接入方案具有硬件接口简单、外围器件少、价格低廉、开发周期短等特点。

The platform of network card interface is designed and realized that can realize data transfer in this paper, as to ARM CPU S3C2410. The Driving program can control Etheinet network chip DM9000 well. Interface design of Etheinet work and driving program controlling the chip are introduced mainly. This mode is provided with simple design,low price,little peripheral equipment and short development cycle.
