Abstract
Computing the Q and the P syndromes, which is needed in RAID 6 systems is effected through use of a single ROM lookup table for the necessary finite field multiplication. In one embodiment, the P and Q syndromes for data that normally arrives with 8-bit words are created by using Galois Field GF(2) arithmetic rather than the conventional GF(2) arithmetic, thereby very significantly reducing the requires size of the lookup table.
