Patent ID: 11108410

Abstract:
A decoder circuit includes a low-density parity-check (LDPC) repository, an LDPC code configurator, and LDPC decoding circuitry. The LDPC repository stores parity-check information associated with one or more LDPC codes. The LDPC code configurator may receive a first LDPC configuration describing a parity-check matrix for a first LDPC code and may update the parity-check information in the LDPC repository to reflect the parity-check matrix for the first LDPC code. The LDPC decoding circuitry may receive a first codeword encoded in accordance with the LDPC code. More specifically, the LDPC decoding circuitry may be configured to read the parity-check information associated with the first LDPC code from the LDPC repository and iteratively decode the first codeword using the parity-check information associated with the first LDPC code.
