ABSTRACT:
A method of implementing a two-dimensional Inverse Discrete Cosine Transform on a block of input data. The method includes 1) generating a performance array for the columns of the input data; 2) performing a column-wise IDCT upon the input data, the IDCT performed in accordance with cases given for each of the columns by the performance array; (3) generating a row performance offset for rows of the input data; and 4) performing a row-wise IDCT upon the result data from the performing of the column-wise IDCT.
