I am using W5300 device with spartan 6 FPga.
I can send and receive data correctly with out error.
But my problem is that the data rate in TCP connection is not more than 6~ 9 Mbps while connection is 100Mbps.
The Bit rate change has been done by change in clock speed in processes for controlling W5300. but when the clock exceeded from 25Mhz, every thing stopped.
i would be thank full if some body help me.
