Abstract
An improved multi-bit error correction system. The inventive error correcting system performs a fast error correction operation on individual bits within multi-bit modules. In a specific implementation, the invention uses Hamming codes and divides an n times m bit data word into m modules, with each module having n bits. Next, the ith bits of each module are combined to form a set of parity bits. Syndrome bits are generated from the parity bits and used to locate errors in the bits and provide an indication of same. Finally, errors in the bits are corrected in a conventional manner to provide corrected data bits.
