Abstract: A data processing system is disclosed including a decoder circuit, syndrome calculation circuit and hash calculation circuit. The decoder circuit is operable to apply a decoding algorithm to a decoder input based on a first portion of a composite matrix to yield a codeword. The syndrome calculation circuit is operable to calculate a syndrome based on the codeword and on the first portion of the composite matrix. The hash calculation circuit is operable to calculate a hash based on a second portion of the composite matrix. The decoder circuit is also operable to correct the codeword on the hash when the syndrome indicates that the codeword based on the first portion of the composite matrix is correct but a second test indicates that the codeword is miscorrected.

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.

Abstract: A method includes receiving a multi-port read request for retrieval of data stored in three memories, each comprising two memory modules and a parity module. The multi-port read request is associated with first data stored at a first memory address, second data stored at a second memory address, and third data stored at a third memory address. When the first memory address, the second memory address, and the third memory address are associated with a first memory module, first data is retrieved from the first memory module, second data is reconstructed using data from a second memory module and a first parity module, and third data is reconstructed using data from a fourth memory module and a seventh memory module. The first data, the second data, and the third data are provided in response to the multi-port read request.
