Abstract: The present inventions are related to systems and methods for data processing, and more particularly to systems and methods for performing data decoding. In one case a data processing system is disclosed that includes a decoder circuit operable to apply a low density parity check algorithm to a decoder input to yield an interim decoded output, where the decoder input is a codeword formed of two bit symbols, and where the decoder input is encoded to yield a last layer including at least two different entry values. In addition, the data processing system includes an inverse mapping circuit operable to remap the interim decoded output to yield an overall decoded output.

Abstract: A data processing system is disclosed including a data decoder circuit, an error handling circuit and a syndrome checker circuit. The data decoder circuit is operable to apply a data decode algorithm to a decoder input to yield a decoded output, and to calculate a syndrome indicating an error level for the decoded output. The error handling circuit is operable to determine whether any errors in the decoded output involve user data bits. The syndrome checker circuit is operable to trigger the error handling circuit based at least in part on the syndrome.
