This paper presents a high-throughput variable-length eight-parallel Reed-Solomon (RS) decoder for high-rate WPAN systems. The proposed architecture can support not only RS (255,239) code but also various shortened RS codes. Moreover, the variable-length architecture provides low latency for various shortened RS codes and the eight-parallel design also provides high data processing rate. Using 90-nm CMOS standard cell technology, the proposed variable-length RS decoder has been synthesized and measured for performance. The proposed RS decoder can provide a maximum 19-Gbps data rate at clock frequency 300 MHz.
