Ethernet MAC

Hello. Looking for a free Ethernet MAC controller with MII (10Mbit). Does Altera has it?

Hi Daixiwen,

Is the Nios system capable of sending UDP packets at 60Mbits/sec on a 100mbps link or do I need to focus my attention on a hardware based solution?

Yes, 60Mbits can easily be done. I can sustain over 900Mbits with UDP on a Cyclone III and TSE and GigE link. I can't see not reaching 90Mbits+ on a 100MB interface. GigE makes a huge difference. Note that at my speeds windows can't keep up. This is with a highly optimized driver, UDP packet generator and a hardware calculated TCP checksum. Without the hardware checksum but using an optimized assembly version I could exceed 500Mbits.
