ABSTRACT:
Circuits, methods, and apparatus that reduce the amount of data transferred between a graphics processor integrated circuit and graphics memory. Various embodiments of the present invention further improve the efficiency of blenders that are included on a graphics processor. One embodiment provides for the storage of a reduced number of subsamples of a pixel when the storage of a larger number of subsamples would be redundant. The number of subsamples that are blended with source data are compressed, thereby reducing the task load on the blenders increasing their efficiency. These methods can be disabled to avoid errors that may arise in certain applications.
