CRC32CB, CRC32CH, CRC32CW, CRC32CX

CRC-32C checksum from byte, halfword, word, or doubleword.

Syntax

CRC32CB  Wd, Wn, Wm    ; Wd = CRC32C(Wn, Rm[7:0])
CRC32CH  Wd, Wn, Wm    ; Wd = CRC32C(Wn, Rm[15:0])
CRC32CW  Wd, Wn, Wm    ; Wd = CRC32C(Wn, Rm[31:0])
CRC32CX  Wd, Wn, Xm    ; Wd = CRC32C(Wn, Rm[63:0])

Where:

Wm

Is the 32-bit name of the general-purpose data source register, in the range 0 to 31.

Xm

Is the 64-bit name of the general-purpose data source register, in the range 0 to 31.

Wd

Is the 32-bit name of the general-purpose accumulator output register, in the range 0 to 31.

Wn

Is the 32-bit name of the general-purpose accumulator input register, in the range 0 to 31.
