摘要： A decoder including a decode module, a matrix module, and a marking module. The decode module receives data and performs a first decoding iteration to decode the data. The first decoding iteration includes generating a first matrix having a first byte. The matrix module generates a second matrix based on the first matrix. The second matrix includes the first and second bytes. The second byte is adjacent and sequentially prior or subsequent to the first byte. The marking module: determines whether the first byte has been correctly decoded; based on determining whether the first byte has been correctly decoded, determines a status of the second byte; and based on the status of the second byte, marks the first byte as an erasure. The decode module, based on the second byte being marked as an erasure, corrects the second byte during the second decoding iteration.

摘要： Aspects of the disclosure provide a signal processing circuit that has fast response time to sudden profile changes in an electrical signal. The signal processing circuit includes a processing path configured to process an electrical signal that is generated in response to reading data on a storage medium, and a feed-forward correction module. The feed-forward correction module is configured to detect a profile variation based the electrical signal in a time window, and correct the electrical signal in the time window based on the detected profile variation.

摘要： Aspects of the disclosure provide a circuit that includes a decoder, an error checking module, and a controller. The decoder is configured to receive codewords, and decode the codewords based on an error correcting code. The error checking module is configured to error-check sectors using an error detecting code in the sectors. Each sector is formed of a plurality of decoded codewords. The controller is configured to store in a memory, when the error checking fails for at least one sector, the decoded codewords and corresponding flags indicative of pass or fail of the decoding of the codewords.
