Abstract
Texture filter logic suitable for determining a minimum or maximum texel value from a plurality of texel values associated with a filter footprint of arbitrary shape and size. In embodiments, logic circuitry includes a plurality of min/max comparison block stages is configured to perform comparisons and determine a min/max value of predetermined number of texel groups. In embodiments, the logic circuitry further includes a number of min/max collectors to accommodate filter footprints having more texel groups than the predetermined number accommodated by the min/max comparison block stages. Iterative comparisons may be performed until all texel groups in the given footprint have been compared. In further embodiments, the logic circuitry outputs four min/max texel values, which may then be further processed with a final comparison stages to arrive at one min/max value for a footprint.
