Abstract

A device includes a low density parity check (LDPC) decoder that is configured to receive a representation of a codeword. The LDPC decoder includes a circuit configured to set a message length of a decoding message at least partially based on an error metric associated with the representation of the codeword. The LDPC decoder also includes a processing unit including a first group of components and a second group of components. The processing unit configured to selectively couple the first group of components to the second group of components based on the message length of the decoding message.
