Ethernet TCP / UDP hardware implemation

Hello everyvbody, sorry for the mistake: Ethernet TCP / UDP hardware implementation I have to send data with a speed of 700MBit/s. I use a Gigabit Phy (Marvel) and a gigabit mac-core (MTIP...

I'm trying to quickly get a near-line rate udp sender/receiver going on a cyclone eval board (with 10/100 PHY). I started by basically merging the Video over IP reference design with the NetworkAccelerationDesign. I managed to get something running well enough to receive garbled UDP messages, but now I'm stuck.

Are the UDP/IP or 100/1000 PHY interface functions used in the Video Over IP ref design tested for use with a 10/100 PHY? The app note (AN374) doesn't provide much info on how to use the PHY interface function in 100 mode.

For example, would all of my system clocks be 25MHz in this mode, instead of 125MHz? And would I leave the upper nibble of the Rx and Tx ports unconnected? Are there any other issues I should be careful of in this mode?

Has anyone else tried to do this?

Thanks!

Tim
