Abstract: Methods and systems for efficient Reed-Solomon (RS) decoding are provided. The RS decoding unit includes both an RS pseudo decoder and an RS decoder. The RS pseudo decoder is configured to correct a small number of errors in a received codeword, while the RS decoder is configured to correct errors that are recoverable by the RS code. The RS pseudo decoder runs in parallel with the RS decoder. Once the RS pseudo decoder successfully decodes the codeword, the RS decoder may stop its processing, thereby reducing the RS decoding latency.
