Abstract
A texture addressing circuit and method for calculating texture coordinates according to various texture addressing modes for texture maps having arbitrary sizes. Texture coordinates are calculated from input texture coordinate values the texture addressing circuit receives and that are located in one of a plurality of predefined input ranges. The texture addressing circuit includes a plurality of coordinate calculation circuits to calculate coordinate output values for each of the input coordinate ranges and to provide the values to a selection circuit from which an output texture coordinate is selected. An output texture coordinate is selected based on the sign of the input texture coordinate and the sign of the calculated texture coordinate values.
