The relaxed half-stochastic (RHS) algorithm is a recently proposed binary message-passing decoding algorithm for low-density parity check codes that can reach the same error rate performance as belief propagation algorithms that exchange LLR messages. Because of its low-complexity interleaver, the RHS algorithm makes it possible to achieve a fully-parallel implementation that can converge to a codeword in only a few clock cycles on average, enabling high throughput and power efficiency. To demonstrate the practicality of the RHS algorithm, we implement a decoder for the popular IEEE 802.3an 10GBASE-T standard. The paper presents details of the hardware implementation, as well as post-layout results for an ASIC implementation in 65nm CMOS technology, which indicate that the decoder can operate at 448 MHz and occupies an area of 4.41 mm2. The results obtained from bit-accurate software simulations show that the decoder meets the latency requirement prescribed by the standard and provides an average throughput of 160 Gbps. |
