Honored Contributorhow can i get about 100Mbps~200Mbps TCP traffic using Ethernet ?
Hi :
I want to use Ethernet to transmit huge of data (after AD processing) to PC. It is better to get about 100Mbps~200Mbps TCP traffic .I think it's hard for Nios II system to get this speeed . Do you have any feasible scheme about this problem ? Does anyone have achieved this speed ? Now ,I have cyclone III and Stratix II ,LAN91C111 and Triple speed Ethernet IP CORE. Best Regards -poseidon13 Replies

Thanks, Poseidon!- Altera_Forum--- Quote Start --- I didn't found this example. Where in wiki nios is it? --- Quote End --- Hi, in Wiki Nios page, try to search for "udp". You will find some links, take a look at those with the tags "udp" and "offload". There is a documentation (some explain about the code) and the example (code and an executable). Hope it can help you :D

I'm sorry, i found the page.
- Altera_Forum--- Quote Start --- nioswiki has a great example using UDP. The example gets line rate at 1Gbps. --- Quote End --- I didn't found this example. Where in wiki nios is it?

You're in for some pain. TCP is non-trivial.

- Altera_Forum--- Quote Start --- The ethernet MAC does use DMA. Jake --- Quote End --- yea ,I found it use SGDMA after reading the TSE document. My boss think it is better to use pure hardware implement to improve faster TCP traffic ,So.i will have a try to write TCP AND ARP model by Verilog or VHDL .Does anyone have seen documents about how to do this ?
