Abstract： |
The method comprises: making an equivalent splitting for each element in integer discrete cosine transform core to get N matrixes; summarizing said N matrixes to get M sub-transformation cores; based on M sub-transformation cores, calculates M sub-transformations; according to the sequence of subscripts from low to high, making combination for the results of M sub-transformations; taking the transformation result of the first processing unit 'DXT' matrix as the 'Y' matrix of the second processing unit; repeating the steps above until getting the integer discrete cosine transformation coefficient. |
