Abstract: A product code decoder to implement a method of bit correction in a codeword buffer to support error correcting code (ECC). The method loads a location entry from a correction queue, where the location entry includes a data word address and bit location information. The method performs a fast path data word address comparison to determine whether data from the data word address is being processed by a previous entry from the correction queue. The method further combines a correction of the data at the data word address specified by the location entry with a correction of a copy of the data being processed based on a previous location entry, in response to a fast path data word address comparison match, and stores the combined data in the codeword buffer.

Abstract: A method and system for implementing error correcting code using a product code decoder. The method and system receive a product code, wherein the product code is a matrix of row and column component codes, generate a plurality of row syndromes column syndromes from the received product code, store the plurality of row syndromes in a row syndrome queue, store the plurality of column syndromes in a column syndrome queue, the column and row syndrome queue to support the plurality of modes of operation corresponding to the plurality of phases of decoding the product code, correct the plurality of row syndromes and columns syndromes in the row and column syndrome queues based on errors detected in respective row and column syndromes and errors detecting in overlapping syndromes, and correct the product code in a codeword buffer at locations corresponding to corrections in the plurality of row syndromes and the plurality of column syndromes.
