P2020 multiword CRC calculation

I'm trying to improve the performance of my software CRC calculation.

I have encountered with an article using multiword CRC implementaion on AMD and Intel CPUs : "Everything we know about CRC but afraid to forget".

In this article they are explaning that multiword calculation can only be done on CPU with multiple ALUs, Like the P2020.


My quastion is, has anyone tried to implement CRC with multiword ? is it possible with P2020 ?



Maybe someone implemented any ither efficient method ?


Thank you,
