Abstract
A register array of a deblocking filter includes a first register configured to store an amount of image data corresponding to a sub-macro block of a macro block to be filtered, a second register configured to store an amount of image data corresponding to a portion of a sub-macro block adjacent a first edge of the macro block to be filtered, and a third register configured to store an amount of image data corresponding to an entire sub-macro block adjacent a second edge of the macro block to be filtered. The first, second and third registers are further configured to support sequential horizontal and vertical component filtering of portions of sub-macro blocks of the macro block to be filtered by sequentially shifting portions of the sub-macro blocks through the first, second and third registers.
