Abstract
A system and method for video data processing for searching a region of overlapping candidate blocks to locate the best match to a comparably sized reference block comprising plurality of tree adder computational structures which each calculate the sum of absolute difference values for the corresponding data pixels in the comparison. The system further comprises a memory and addressing configuration comprising a dual part RAM, a funnel shifter, and control logic to supply the necessary data pixel values to allow the plurality of tree adders to compute the sum of absolute difference values for adjacent locations concurrently. Another aspect of the system and method for video processing is accumulating two values representing mathematical comparisons of two multi-dimensional images performed in a pixel-wise manner to determine which of the comparison produces less of a difference between the compared images.
