OPERATION CONTROL DATA GENERATION METHOD OF LDPC DECODER, AND LDPC DECODER

摘要

PPROBLEM TO BE SOLVED: To provide a general purpose LDPC decoder by generating control data for the read from a memory of data required for an operation and the write of the data to the memory from a check matrix in order to constitute the general purpose LDPC decoder corresponding to an optional check matrix. PSOLUTION: For an imparted check matrix, rows with 1 for each column are calculated, and data for which column numbers, a plurality of row numbers for a number equivalent to calculated column weight and connection information indicated by 1 are grouped for each of the same row number are generated and used as address control data for the read from a β storage memory at the time of an α operation and the write to an α storage memory of an operation result.
