| Resumo: | [EN] Several 100Gbps Ethernet standards for backplane, copper cables and fiber optic that include forward error correction based on Reed-Solomon (RS) codes have been recently approved, being an important issue not only to achieve high data rates but also to keep a low latency. This paper presents two low-latency and high-throughput RS decoders suitable for those standards. We propose the use of a modified Enhanced Parallel iBM Algorithm as the key equation solver (KES) stage and a novel architecture for the error evaluation block, which is suited for this KES. Implementation results are given for the RS(528,514) and RS(544,514) codes over GF(210) that reach 100Gbps when implemented in a 90nm CMOS process. |
