ROHC CRC Calculation

[rajavel.rv]

Hi all,

I have a polynomial equation of CRC(cyclic redundancy check) for ROHC compression and decompression technique, the polynomial equation equation is shown below,

CRC 3-BIT : C(x) = 1 + x + x^3
CRC 7-BIT : C(x) = 1 + x + x^2 + x^3 + x^6 + x^7
CRC 8-BIT : C(x) = 1 + x + x^2 + x^8

Here, the problem is how can i write code for verilog HDL using this polonimal, what is input and input sizes, but the output is CRC3 = 3bit, CRC7 = 7bit, CRC8 = 8bit.

note : RFC Document of ROHC implementation not having a clear details for this CRC technique.

Anybody have a idea please give me a suggestion and send the link details.

Thanks Advance,

Best Regards,
