How to divide input in parallel crc?

Question

I am trying to understand the working of a parallel crc using look up tables, I could get the basic sarwate code running correctly but I am having a lot of confusion when it comes to appending or prepending zeros.

I am trying to use this code for a parallel crc generation but I am confused on how to divide which part of the input data and append zeros.

Please help, I am really stuck here.

Please edit your question and show the code you already have. Also describe what exactly does not work with this code or where you have doubts. — Holger Just, Aug 29 '17 at 16:37
FYI: `initial` in table1 should be `always @*`. Otherwise it will only be evaluated at time 0 and likely before receiving the input data. — Greg, Aug 29 '17 at 18:40

You can see how to combine CRCs computed in parallel by looking at the source code for zlib's crc32_combine() routine. You do not need to prepend or append zeros.
