Abstract
This brief presents an area-efficient relaxed half stochastic non-binary low-density parity-check (NBLDPC) decoder. Furthermore, the hardware complexity of variable node units (VNUs) is reduced through a truncated architecture, which only keeps the most reliable n probability density functions. To accelerate the majority logic decoding of difference set low density parity check codes the error detection in memory applications was proposed. This is useful as majority logic decoding can be implemented serially with simple hardware but requires a large decoding time. For memory applications, the increase of the memory access time takes place. S-Box Codes are the class of linear block codes which provide near capacity performance on large collection of data transmission channels.
