Techniques are provided for performing Galois field arithmetic to detect errors in digital data stored on disks. Two 12-bit numbers or two 10-bit numbers are multiplied together in Galois field using tower arithmetic. In the 12-bit embodiment, a base field GF(2) is first extended to GF(23), GF(23) is...http://www.google.fr/patents/US7774679?utm_source=gb-gplus-shareBrevet US7774679 - Techniques for performing reduced complexity galois field arithmetic for correcting errors
