Looking for example for remote PC connection to Ethernet using DE2-115 Cyclone II & NIOS II

I am a student in the university doing my final project using the Altera DE2-115 board (Cyclone II). I am looking for a design example of using remote PC connection through Ethernet connection using ...

This board is manufactured by Terasic. There is everything you need inside the CD-ROM, which you can download from their website. If you want a TCP/IP protocol, you can start from the webserver project.

Actually there are 2 ways to implement a TCP/IP stack using a NIOSII proc. The first one uses a Real time OS as done inside the example of Terasic and from my experience, it is not straight forward.

The other way uses the uIP implements the stack only and pools the MAC interface to process each ethernet frame. https://en.wikipedia.org/wiki/UIP_(micro_IP)

You can search for an implementation on Intel FPGA device, somes already did it.

I used the latter by the past and it works way faster than the first mentionned. (about 50MB/s with a GbE ethernet interface)

Good luck.
