This paper presents a computationally efficient iterative Reed-Solomon (RS) decoder, which is suitable for software implementations on processors with instruction extensions for Galois field multiplication. Simulation models of proposed instructions were included into a processor simulator and performance of RS decoding was analyzed. The method has been validated for both Digital Video Broadcasting (DVB-T/H) and WiMAX and the method provides a total link budget improvement of up to 1 dB.
