A programmable, reconfigurable Reed-Solomon encoder/decoder allows for flexible reprogramming of encoders and decoders for a variety of applications. The standard Reed-Solomon parameters of the Galois Field order, the primitive polynomial, the number of symbols for each codeword of the transmitted and source data are settable via writable registers. The Reed-Solomon encoder/decoder may be coupled to a digital signal processor which specifies the parameters loaded in the writable registers via data register space of data memory space. The decoder and encoder parameters are separately specified and the decoder and encoder can run simultaneously and independently.
