Algorithms and Architectures for Soft -Decoding Reed -Solomon Codes

Finally, the applicability of soft-decoding for disk-drive applications is studied. Based on performance improvements and complexity requirements, generalized minimum distance decoding with maximum a priori soft-detection is selected, and the corresponding architecture is developed. The generalized minimum distance decoder is expected to give 0.5 dB gain over a hard-decoder at the target bit error-rate of 10-12 for the disk-drive channel. The architecture is synthesized using the Virtual Silicon standard cell library in a 0.13-mum CMOS process. It has an area of 7.29 mm² and achieves a throughput of 8 Gbps.
