摘要： The texture engine, provided in this disclosure, comprises a texel location calculator, a texture cache unit, and a video processing unit. The texel location calculator receives a texture and video request for a pixel, including location information of texture data for the pixel in a texture map stored in a memory unit and information of video processing required for the pixel. The texel location calculator computes memory addresses of the texture data in the memory unit and graphics data required for the pixel when performing the video processing specified in the texture and video request in the memory unit. The texture cache unit retrieves a copy of the graphics data and texture data from the memory unit with the memory addresses computed by the texel location calculator. The video processing unit receives the graphics data to perform the video processing specified in the texture and video request on the graphics data.
