Abstract: A method and apparatus for motion compensation of digital video data with a texture mapping engine is described. In general, the invention provides motion compensation by reconstructing a picture by predicting pixel colors from one or more reference pictures. The prediction can be forward, backward or bidirectional. The architecture described herein provides for reuse of texture mapping hardware components to accomplish motion compensation of digital video data. Bounding boxes and edge tests are modified such that complete macroblocks are processed for motion compensation. In addition, pixel data is written into a texture palette according to a first order based on Inverse Discrete Cosine Transform (IDCT) results and read out according to a second order optimized for locality of reference. A texture palette memory management scheme is provided to maintain current data and avoid overwriting of valid data when motion compensation commands are pipelined.

Abstract: A method and apparatus for image scaling is provided. A 3D pipeline comprises a command stream controller to enable a rectangle mode. The 3D pipeline including a windower to produce addresses for the rectangle defined by the vertices. A filter interpolates between neighboring points, based on relative location, to generate attributes for each pixel. A color calculator aligns output data and writes the output data to a destination surface.
