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. Jake

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

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 ?

Thank you ,But I have to use TCP that Provide reliably data transmit.

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