摘要:
A method and apparatus which includes a graphics accelerator, circuitry responsive to pixel texture coordinates to select texels and generate therefrom a texture value for any pixel the color of which is to be modified by a texture, a cache to hold texels for use by the circuitry to generate texture value for any pixel, a stage for buffering the acquisition of texel data, and control circuitry for controlling the acquisition of texture data, storing the texture data in the cache, and furnishing the texture data for blending with pixel data.
