Area-efficient Reed-Solomon decoder design for 10-100 Gb/s applications

With the extensive applications in high-speed communication systems, the current high-throughput Reed-Solomon decoders are required to achieve the target data rates from 10 Gb/s to 100 Gb/s with low hardware complexity. In this paper, pipeline interleaving inversionless Berlekamp-Massey (PI-iBM) algorithm and pipeline interleaving reformulated inversionless Berlekamp-Massey (PI-RiBM) algorithms for decoding Reed-Solomon codes are presented. Based on these two new algorithms PI-iBM and PI-RiBM Reed-Solomon decoders targeted at 10-100 Gb/s applications are developed. Compared with previously published works, the proposed designs can achieve very high throughput with relatively low hardware complexity. Thus they are well suited for modern high data rate communication systems.
