crc32 calculation

i am using spartan 3E board to transmit UDP packets to pc.I can see that the packet is transmitted but it is dropped by my card because i guess my CRC is invalid.

I cannot find a way to feed bytes to crc32 generator as there are many things to be considered like bit reversal and complementing and what n what not..

Can anyone shed some light on it .
Thanks

Re: crc32 calculation

hey big dogguru!
i need your help once again. I have tried the code attached with your link, i have tried the code present at outputlogic.com, haven't tried the one at opencores yet but the thing is that i am not getting the same result with both of these codes. The results which i get using crc32 calculator are different from those given by these codes.

i have no idea what's the problem :s kindly help me out ..

thanks
