ABSTRACT:
A first data buffer stores LEVEL representing the size of a non-zero coefficient value of the variable length coded/run length coded data input from the outside. A write controller writes the LEVEL to the first data buffer in decoded order. An initial address calculator calculates the initial address of the LEVEL from the TotalCoeff and the number of zero coefficients of the total_zeros. An address holder determines and holds the address of the LEVEL corresponding to data based on the initial address and the number of zero coefficients by the run_before. A read controller reads the LEVEL from the first data buffer based on the address information. A selector selects the data of either the LEVEL stored in the first data buffer or the zero coefficients based on the address information. A post-stage processor post-stage processes the data selected by the selector.
