Low-density parity-check codes achieve coding performance which approaches the Shannon limit. An (8158,7136) encoder was implemented in a five-metal, 0.25-mum CMOS process. Use of generator polynomial reconstruction, partial product multiplication and functional sharing in the parity register results in a highly efficient design. Only 1492 flip-flops along with a programmable 21-bit look-ahead scheme are used to achieve an 860-Mb/s data throughput for this rate 7/8 LDPC code. A comparable two… CONTINUE READING
