High-Throughput LDPC Decoders Using A Multiple Split-Row Method

Abstract

We propose the "multi-split-row'" LDPC decoding method which allows further reductions in routing complexity, greater throughput, and smaller circuit area implementations compared to the previously proposed split-row decoding method. Multi-split-row is especially useful for regular high row weight LDPC codes. A 2048-bit full parallel decoder is implemented in a 0.18 μm CMOS technology using standard MinSum, split-row-2 and split-row-4 methods. The split-row-4 decoder delivers 7.1 Gbps throughput with 15 decoding iterations, and has 3.2 times smaller circuit area and 5.2 times higher throughput than the standard MinSum decoder.
