| 摘 要： | 以NiosⅡ嵌入式软处理器为核心，利用以太网控制器LAN91C111设计了基于NiosⅡ嵌入式软处理器的
以太网通信接口。提供了以太网接口具体的硬件设计方案，分析了lwIP协议（精简的TCP/IP协议），并根据lwIP
协议进一步编写了以太网接口的驱动程序。与传统的嵌入式设计方案相比，该方案具有很强的扩展性和灵活性，
降低了软件的开发成本以及硬件实现风险

| Abstract: | An Ethernet interface based on Nios II soft-core and Ethernet controller chip LAN91C111 was designed. The hardware design was provided in a detailed way and the protocol of lwIP was analyzed. At the same time, the software was also given based on the lwIP. Compared with traditional project, this design has a strong expansibility and agility. It also reduces the cost that used to develop the software and the risk in the course of the hardware development. |
