ABSTRACT:
A technique for performing an anti-aliasing operation by multiple graphics processing units includes utilizing a first graphics processing unit to generate a first subset of filtered data resulting from performing anti-aliasing processing and similarly utilize a second graphics processing unit to generate a second subset of filtered data. The first graphics processing unit then pulls a first portion of the second subset of filtered data from a first memory block of a temporary buffer and blends such pulled data with a first portion of the first subset of filtered data. Overlapping in time with the pulling and blending operation of the first graphics processing unit, the second graphics processing unit pulls a second portion of the first subset of filtered data from a second memory block of the temporary buffer and blends such pulled data with a second portion of the second set of filtered data.
