ABSTRACT:
Disclosed are methods and apparatus for accomplishing the fetching or sampling of channels of pixels or texels such as neighboring pixels or texels or non-neighboring pixels or texels in a simultaneous operation in order to achieve optimization of the performance of a texture pipeline. In particular, logic is disclosed including selector logic configured to retrieve data including a plurality of channels from each of a plurality of pixels or texels and operable to select one channel from the plurality of channels of the data from each of the pixels or texels. The logic also includes combination logic configured to combine two or more of the selected channels into a single vector, such as an RGBA vector representing the color.
