针对传统嵌入式以太网系统存在的数据传输速率低、硬件不能升级、实时性和通用性不足等问题，提出了基于内嵌有Nios II CPU 的Altera Cyclone系列FPGA的以太网控制器设计方案。该方案针对以太网协议利用Quartus II和Nios II IDE为开发工具，对硬件进行重新配置，以提高系统集成度；采用SOPC技术构建了嵌入式网络硬件平台；基于μC／OS-II实现了NicheStack TCP／IP协议栈的移植及顶层应用程序的编写。系统测试结果表明，数据能够以400 Mb／s的速率正确收发，满足了以太网通信速率的要求，并可根据实际情况灵活配置。

In order to solve the problems of the traditional embedded Ethernet system,such as low data transmission rate,hardware cannot be upgraded,poor real-time and universality etc,the Ethernet controller design scheme based on Altera Cyclone series FPGA with Nios II CPU was proposed.The design aimed at Ethernet protocal using the Quartus II and Nios II IDE as the development tools for reconfiguration of the hardware in order to reduce the cost and improve the system integration.The SOPC technology was used to construct the embedded network hardware platform and based on μC/OS-II to achieve the migration of Ni-cheStack TCP/IP and compiling of the top application.The system test results showed that the design met the requirement of the Ethernet communication rate at the data rate of about 400 Mb/s,and could be flexi-ble configurated according to actual situation.
