Claim One:
1. A circuit arrangement, comprising: a memory storage element; and processing logic coupled to the memory storage element and configured to perform anisotropic filtering using a texture including texture data stored in a memory address space, the processing logic configured to perform anisotropic filtering based upon a plurality of sample points defined along a line of anisotropy for the texture, determine a first length representative of a distance in texels between a first sample point and a second sample point of the plurality of sample points along a first axis, determine a second length representative of a distance in texels between the first sample point and the second sample point, and the processing logic further configured to initiate a prefetch of texture data for a sample point among the plurality of sample points into the memory storage element using a stride value representative of a distance in the memory address space between sample points in the texture, wherein the stride value is based at least in part on the first length and the second length.
