MATRIX TECHNIQUE LEADS TO DIRECT ERROR CODE IMPLEMENTATION.

Error detecting and correcting codes are typically implemented as a consequence of the polynomial division algorithm. An alternative viewpoint, the H-matrix perspective, suggests a matrix representation that is ideally suited to ROM based implementation. This approach is especially advantageous for use with relatively short blocks of data as, for example, when reading and writing random access memory. Attention to the specific details of an ongoing example traced through complete development of the H-matrix perspective gives further insight into system behavior and potential design techniques. Overall, the procedure is essentially unclocked, very fast, and conducive to implementation as a single LSI device.
