Abstract
A decoder circuit includes an input to receive a first codeword encoded based on a quasi-cyclic low-density parity-check (QC LDPC) code and a plurality of memory banks to store the received codeword. Each column of the received codeword is assigned to one of the plurality of memory banks based at least in part on an order of the plurality of columns in the received codeword. A first reordering stage is to change the memory bank assignment for one or more of the plurality of columns by reordering the columns in the received codeword. An LDPC decoder is to decode the reordered codeword stored in the plurality of memory banks based at least in part on the QC LDPC code. A second reordering stage is to output the decoded codeword from the plurality of memory banks based at least in part on an order of the columns in the first codeword.
