57 / 212 page  crcword 57/212 ® crcword calculate CRC on word Code: 27 F4 Description: Generate a CRC (cyclic redundancy check) checksum from Areg. Breg contains the previously accumulated checksum and Creg the polynomial divisor (or ‘generator’). The new CRC checksum, the polynomial remainder, is calculated by repeatedly (BitsPerWord times) shifting the accumulated checksum left, shifting in successive bits from the Areg and if the bit shifted out of the checksum was a 1, then the generator is exclusive-ored into the checksum. Definition: Areg ′← temp(BitsPerWord) Breg ′← Creg Creg ′← undefined where temp(0) = Breg for i = 1.. 32 temp(i) = (temp(i -1) << 1) + Areg BitsPerWord-i) ⊗ (Creg × temp(i −1) BitsPerWord-1) Error signals: none Comments: Secondary instruction.
