How GPUs can outperform ASICs for fast LDPC decoding

  title={How GPUs can outperform ASICs for fast LDPC decoding},
  author={Gabriel Falc{\~a}o Paiva Fernandes and V{\'i}tor Manuel Mendes da Silva and Leonel Sousa},
Due to huge computational requirements, powerful Low-Density Parity-Check (LDPC) error correcting codes, discovered in the early 1960s, have only recently been adopted by emerging communication standards. LDPC decoders are supported by VLSI technology, which delivers good parallel computational power with excellent throughputs, but at the expense of significant costs. In this work, we propose an alternative flexible LDPC decoder that exploits data-parallelism for simultaneous multicodeword… CONTINUE READING
