Abstract
The present invention (10) substantially overcomes many of the problems associated with prior art error detection codes by providing a novel approach to detecting and correcting multiple bit errors. The invention (10) organizes the data word into a matrix of n by m bits, where n is the number of m bit groups. Parity bits are generated for each column and each row and used to detect single, double and triple bit errors.
