【摘要】 以太网技术在嵌入式系统中应用广泛。讨论基于Altera公司的SOPC技术,设计和实现嵌入式环境下的以太网终端。在SOPC Builder环境下利用Nios Ⅱ处理器、三速以太网等IP,构建满足嵌入式系统要求的以太网终端。并且基于Nios Ⅱ处理器移植了μC/OS-II操作系统,开发了底层硬件的驱动程序,移植了LwIP轻量级网络协议栈,实现了与PC机之间的网络互联。更多还原

【Abstract】 Ethernet technology is wildly used in embedded system.The design and implement of embedded ethernet node based on SOPC technology of Altera is presented in this thesis.In the environment of SOPC Builder,an ethernet node with IPs including Nios Ⅱ processor and triple speed ethernet to meet the demands of embedded system is built,and transplanted μC/OS-Ⅱ Operating System based on Nios Ⅱ processor,developed driver of hardware,transplanted LwIP(Light weight IP) network protocol stack,implemented the connection with PC network card.更多还原
