We propose the Multi-Split method which allows further reductions in routing complexity and results in higher throughput, smaller area decoder implementations compared to previously proposed Split-Row decoding method. Multi-Split is especially useful for regular high row weight LDPC codes. A 2048-bit full parallel decoder is implemented in a 0.18 um CMOS technology using standard MinSum, Split-2 and Split-4 methods. The Split-4 decoder delivers 7.1 Gbps throughput with 15 decoding iterations and is 3.2 times smaller, has 2.9 times shorter wires, and delivers 5.2 times higher throughput than the standard MinSum decoder.
