Abstract: One embodiment of the present invention includes a method for generating accumulated bounding boxes for graphics primitives. The method includes generating a first bounding box associated with a first graphics primitive. The method further includes, for each graphics primitive included in a first set of one or more additional graphics primitives, determining that the graphics primitive is within a threshold distance of the first bounding box, and adding the graphics primitive to the first bounding box. The method further includes determining not to add a second graphics primitive to the first bounding box. The method further includes generating a second bounding box associated with the second graphics primitive. Finally, the method includes transmitting the first bounding box to a tiling unit via a crossbar. One advantage of the disclosed embodiments is that multiple bounding boxes are combined to generate an accumulated bounding box that is then transferred across the crossbar.

Abstract: A system, method, and computer program product are provided for a dynamic display refresh. In use, a state of a display device is identified in which an entirety of an image frame is currently displayed by the display device. In response to the identification of the state, it is determined whether an entirety of a next image frame to be displayed has been rendered to memory. The next image frame is transmitted to the display device for display thereof, when it is determined that the entirety of the next image frame to be displayed has been rendered to the memory. Further, a refresh of the display device is delayed, when it is determined that the entirety of the next image frame to be displayed has not been rendered to the memory.
