Abstract
The present embodiments relate to Reed-Solomon encoding, and to circuitry for performing such encoding, particularly in an integrated circuit. A Reed-Solomon encoder circuit may receive a message with data symbols and compute a partial syndrome vector by multiplying the data symbols with a first matrix. The Reed-Solomon encoder circuit may further compute parity check symbols by solving a system of linear equations that includes the partial syndrome vector and a second matrix. As an example, the second matrix may be decomposed into a lower triangular matrix and an upper triangular matrix, and the parity check symbols may be computed by performing a forward substitution and a backward substitution using the lower and upper triangular matrices. The Reed-Solomon encoder circuit may generate a Reed-Solomon code word by combining the data symbols and the parity check symbols, and provide the Reed-Solomon code word at an output port.
