Method for controlling message-passing algorithm based decoding operation by referring to statistics data of syndromes of executed iterations and related control apparatus thereof

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.

1. A method for controlling a message-passing algorithm (MPA) based decoding operation, comprising:
updating a counter number by counting a number of successive times a syndrome of a current iteration is identical to a syndrome of a previous iteration, in order to gather 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.
