High Throughpu Ethernet connection

The basic IP stack (LWIP) that comes with Nios II is not known for its perfromance, but it does feature the sockets API, works resonably well, and the best part is that it is free. Altera has produced a reference design for Nios II & high-speed ethernet with the combination of Nios II, and third party IP stack and ethernet MAC IP. You can check out the specifications and performance here (I believe there is also a reference design you can download): http://www.altera.com/corporate/news_room/...interniche.html (http://www.altera.com/corporate/news_room/releases/products/nr-interniche.html)
