Abstract: Some implementations provide systems, devices, and methods for rendering a plurality of primitives of a frame, the plurality of primitives being divided into a plurality of batches of primitives and the frame being divided into a plurality of bins. For at least one batch of the plurality of batches the rendering includes, for each of the plurality of bins, rendering primitives of a first sub-batch rasterizing to that bin, and for each of the plurality of bins, rendering primitives of a second sub-batch rasterizing to that bin.

Abstract: A processing device and a method of tiled rendering of an image for display is provided. The processing device includes memory and a processor. The processor is configured to receive the image comprising one or more three dimensional (3D) objects, divide the image into tiles, execute coarse level tiling for the tiles of the image and execute fine level tiling for the tiles of the image. The processing device also includes same fixed function hardware used to execute the coarse level tiling and the fine level tiling. The processor is also configured to determine visibility information for a first one of the tiles. The visibility information is divided into draw call visibility information and triangle visibility information for each remaining tile of the image.

Abstract: A technique for performing ray tracing operations is provided. The technique includes initiating bounding volume hierarchy traversal for a ray against geometry represented by a bounding volume hierarchy; identifying multiple nodes of the bonding volume hierarchy for concurrent intersection tests; and performing operations for the concurrent intersection tests concurrently.

Abstract: Devices and methods method of tiled rendering are provided which comprises dividing a frame to be rendered, into a plurality of tiles, receiving commands to execute a plurality of subpasses of the tiles, interleaving execution of same subpasses of multiple tiles of the frame by executing one or more subpasses as skip operations, storing visibility data, for subsequently ordered subpasses of the tiles, at memory addresses allocated for data of corresponding adjacent tiles in a first direction of traversal and rendering the tiles for the subsequently ordered subpasses using the visibility data stored at the memory addresses allocated for corresponding adjacent tiles in a second direction of traversal, opposite the first direction of traversal.

Abstract: Techniques for performing rendering operations are disclosed herein. The techniques include performing two-level primitive batch binning in parallel across multiple rendering engines, wherein tiles for subdividing coarse-level work across the rendering engines have the same size as tiles for performing coarse binning.

Abstract: A method of tiled rendering of an image for display is provided which comprises receiving an image comprising one or more three dimensional (3D) objects and executing a visibility pass for determining locations of primitives of the image. The method also comprises executing, concurrently with the executing of the visibility pass, front end geometry processing of one of the primitives determined, from the visibility pass, to be in a first one of a plurality of tiles of the image and executing, concurrently with the executing of the visibility pass, back end processing of the one primitive in the first tile.

Abstract: A technique for executing commands for an accelerated processing device is provided. The technique includes obtaining an iteration number and predication data from metadata for an iterative indirect command buffer; for each iteration indicated by the iteration number, performing commands of the iterative indirect command buffer as specified by the predication data; and ending processing of the iterative indirect command buffer in response to processing a number of iterations equal to the iteration number.
