Abstract: A method to process tiles of a screen space includes determining a tile-processing order for tiles of a first batch of primitives based on a tile-processing order for a second batch of primitives in which the second batch of primitives are processed prior to the first batch of primitives. The tiles of the first batch of primitives are processed based on the tile-processing order determined for the tiles of the first batch of primitives. The tile-processing order is updated as tiles of the first batch of primitives are pushed to a backend processing portion of a graphics processing unit. In one embodiment, determining the tile-processing order for the tiles of the first batch of primitives include arranging the tiles of the first batch of primitives that have a same screen-space as tiles of the second batch of primitives based on a most-recently-processed-tile-to-a-least-recently-processed tile order of the second batch of primitives.

Abstract: A system and a method are disclosed that reduce primitive overdraw in a GPU. An occlusion index (OI) for a first tile of a batch of graphical data. In one embodiment, the first tile is bypassed from an early coverage discard (ECD) first-in, first-out (FIFO) if the OI for the first tile is less than a first threshold, otherwise the first tile is entered into the ECD FIFO. The first tile is also bypassed from the ECD FIFO if the OI for the first tile is greater than a second threshold that is greater than the first threshold. In another embodiment, a queue length is logically changed for the first tile in the ECD FIFO if the OI for the first tile is greater than the first threshold and less than or equal to a third threshold that is greater than the first threshold and less than the second threshold.

Abstract: A graphics pipeline of a graphics processing unit includes a compressor that receives one or more attributes (positional and non-positional) of a vertex that is output from a vertex shader. The compressor determines a format of the one or more attributes, and separates each attribute into parts based on the format of the attribute. The compressor compresses each respective part of the attribute based on a type of the part. The compressed parts of the attribute are stored in an attribute storage.

Abstract: A computer-implemented redundant-coverage discard method and apparatus for reducing pixel shader work in a tile-based graphics rendering pipeline is disclosed. A coverage block information (CBI) FIFO buffer is disposed within an early coverage discard (ECD) logic section. The FIFO buffer receives and buffers coverage blocks in FIFO order. At least one coverage block that matches the block position within the TCPM is updated. The TCPM stores per-pixel primitive coverage information. The FIFO buffer buffers a moving window of the coverage blocks. Incoming primitive information associated with the coverage blocks is compared with the per-pixel primitive coverage information stored in the tile coverage-primitive map (TCPM) table at the corresponding positions for the live coverages only. Any preceding overlapping coverage within the moving window of the coverage blocks is rejected. An alternate embodiment uses a doubly linked-list rather than a FIFO buffer.
