Abstract

A device includes a low density parity check (LDPC) decoder that configured to receive a representation of a codeword. The LDPC decoder includes a message memory configured to store decoding messages, multiple data processing units (DPUs), a control circuit, and a reording circuit. The control circuit is configured to enable a first number of the DPUs to decode the representation of the codeword in response to a decoding mode indicator indicating a first decoding mode and to enable a second number of the DPUs to decode the representation of the codeword in response to the decoding mode indicator indicating a second decoding mode. The reordering circuit is configured to selectively reorder at least one of the decoding messages based on the decoding mode indicator.
