Abstract:
A mapping engine maps general processing clusters (GPCs) within a parallel processing subsystem to screen tiles on a display screen based on the number of enabled streaming multiprocessors (SMs) within each GPC. A given GPC then generates pixels for the screen tiles to which the GPC is mapped. One advantage of the disclosed technique is a given GPC performs a fraction of the processing tasks associated with the parallel processing subsystem that is roughly proportional to the fraction of SMs included within the GPC.
