Abstract:
1. A method comprising: receiving a stream of codewords from a hard disk controller; using a low-density parity check coding algorithm, encoding at least a first codeword from the stream of codewords; based at least in part on encoding at least the first codeword, transmitting a write data ready signal to the hard disk controller; responsive at least in part to transmitting of the write data ready signal to the hard disk controller, receiving a write gate signal from the hard disk controller, wherein the write gate signal is configured to request a read/write channel to write at least a first part of the stream of codewords to a media; receiving a symbol count signal from the hard disk controller, wherein the symbol count signal indicates a number of symbols to be written corresponding to the write gate signal; and responsive at least in part to receipt of the write gate signal from the hard disk controller, requesting the read/write channel to write at least the first part of the stream of codewords to the media, wherein the first part of the stream of codewords corresponds to the number of symbols to be written corresponding to the write gate signal.
