High-Performance Variable-Length Reed-Solomon Decoder Architecture for Gigabit WPAN Applications

This paper presents a universal architecture for 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 various shortened RS codes. Moreover, variable-length architecture provides variable low latency for various shortened RS codes and the eight-parallel design also provides high data processing rate. Using 90- CMOS standard cell technology, the proposed RS decoder has been synthesized and measured for performance. The proposed RS decoder can provide a maximum 19- data rate at clock frequency 300 .
