基于NiosⅡ软核处理器的嵌入式以太网接口设计

Design of Ethernet Interface Based on Nios Ⅱ

简要介绍了NiosⅡ系统及其软硬件设计方法。在μC／OS-Ⅱ操作系统和NicheStackTCP／IP协议栈的基础上，设计实现了以NiosⅡ软核处理器为中心，以LAN91C111为网络控制器的嵌入式以太网接口。

This paper describes Nios Ⅱ system and its develop methods. An implement ofethemet interface is also presented, which is designed by using LAN91C111 based onμC/OS-Ⅱ operating system and NicheStack TCP/IP stacks.
