ABSTRACT:
Two pairs of deblock instructions for performing deblock filtering on a horizontal row of pixels according to the H.264 (MPEG 4 part 10) and VC1 video codec algorithms. The first instruction of each pair has three 128-bit operands comprising the 16-bit components of a horizontal line of 8 pixels crossing a vertical block edge between pixels4and5in a YUV image, a series of filter threshold parameters, and a 128-bit destination operand for storing the output of the first instruction. The second instruction of each pair accepts the same 16-bit components as its first input, the output of the first instruction as its second input and a destination operand for storing an output of the second instruction as its third input. The instruction pairs are intended for use with the H.264 or VC1 video codecs respectively.
