Abstract
Methods and hardware for texture address generation receive fragment coordinates for an input block of fragments and texture instructions for the fragments and calculating gradients for at least one pair of fragments. Based on the gradients, the method determines whether a first mode or a second mode of texture address generation is to be used and then uses the determined mode and the gradients to perform texture address generation. The first mode of texture address generation performs calculations at a first precision for a subset of the fragments and calculations for remaining fragments at a second, lower, precision. The second mode of texture address generation performs calculations for all fragments at the first precision and if the second mode is used and more than half of the fragments in the input block are valid, the texture address generation is performed over two clock cycles.
