Abstract

A circuit and method includes a global parity symbol in a multi-way interleaved Reed-Solomon code implementation to enhance error-detection capability of the Reed-Solomon code. In one embodiment, the global parity symbol is computed over both the data symbols and the check symbols of the Reed-Solomon code, thereby providing data detection capability for errors occurring in the check symbols.
