Abstract
A CMOS Reed-Solomon decoding circuit calculates syndromes, executes a Berlekamp algorithm, performs a Chien Search, and corrects a delayed version of the received data according to a calculated magnitude of error. The circuit is optimized in terms of chip territory and circuit complexity. Signals are provided to indicate uncorrectable packet errors and other transmission errors.
