how can i get about 100Mbps~200Mbps TCP traffic using Ethernet ?

[Altera_Forum]

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 -poseidon

application note 440 (http://www.altera.com/literature/an/an440.pdf), page 18, gives some results that you can expect with a Nios CPU on a Stratix II.

nioswiki has a great example using UDP. The example gets line rate at 1Gbps.

The ethernet MAC does use DMA.

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

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

Oh, i'm sorry. :p:p:p 

 Thanks, Poseidon!
