How many bits do you process in one clock cycle?
I have implemented the CRC32 with 64 bits in one clock cycle and can run it with 156.25 MHz in a Startix V without any problems. And this is a straight forward implementation without any pipelining.
By the way it is possible to pipeline CRC computations. There is a bunch of publications that describe how to do this. The one that I currently favor is:
y. sun, m.s. kim, "a table-based algorithm for pipelined crc calculation," 2010 ieee international conference on communication (

I am trying to do CRC on full packet (8 bit * 53 = 424)
I'm still not understanding, how does it possible to make the multiply CRC calculation during 1 cycle and with "signals" when your are dependent of the previous value. Every time I have to wait to the end of the cycle in order to get the result
