CRC32
CRC32
Description
Calculate the CRC of register D[a] and the inverse of register D[b] and put the result in register D[c].
The CRC polynomial used is the CRC-32 polynomial as defined in the IEEE 802.3 standard. The initial value of
D[b] should be zero
CRC32D[c], D[b], D[a] (RR)
D[c] = crc32(D[b, D[a]);
