ABSTRACT:
The number of crossbars in a graphics processing unit is reduced by assigning each of a plurality of pixels to one of a plurality of pixel shaders based at least in part on a location of each of the plurality of pixels within an image area, generating an attribute value for each of the plurality of pixels using the plurality of pixel shaders, mapping the attribute value of each of the plurality of pixels to one of a plurality of memory partitions, and storing the attribute values in the memory partitions according to the mapping. The attribute value generated by a particular one of the pixel shaders is mapped to the same one of the plurality of memory partitions.
