摘要： A method for controlling a message-passing algorithm (MPA) based decoding operation includes: gathering statistics data of syndromes obtained from executed iterations; and selectively adjusting a decoding operation in a next iteration to be executed according to the statistics data. A control apparatus for controlling an MPA based decoder includes an adjusting circuit and a detecting circuit. The detecting circuit is coupled to the adjusting circuit, and used for gathering statistics data of syndromes obtained from executed iterations, and selectively controlling the adjusting circuit to adjust a decoding operation in a next iteration to be executed according to the statistics data.

摘要： A method for determining a parity check matrix utilized in a flash memory system is disclosed. The parity check matrix comprises M×N blocks. The method includes generating a first set of candidate blocks as candidates of a first set of blocks of the M×N blocks; calculating a plurality of first estimated results corresponding to the first set of candidate blocks; determining content of a first block of the M×N blocks according to a best result of the first estimated results; generating a second set of candidate blocks as candidates of a second set of blocks of the M×N blocks; calculating a plurality of second estimated results corresponding to the second set of candidate blocks by considering the content of the first block; determining content a second block of the M×N blocks according to the second estimated results.
