  • Publication number: 20240037692
    Abstract: When performing tile-based rendering in a graphics processing system, lists indicative of fragments to be processed are maintained for respective sub-regions of tiles to be rendered, with each list entry including, inter alia, at least an indication of the coverage within the tile sub-region of the group of fragments that the list entry represents, and an indication of whether the group of fragments that the list entry represents is eligible to undergo particular processing operations. The coverage information and eligibility information for the list entries is then used to control the processing of fragments for sub-regions of a tile, in such a way as to ensure that processing order dependencies are enforced and met.

  • Publication number: 20230298264
    Abstract: In a tile-based graphics processor when rendering a tile of a render output, which sub-regions, of a plurality of sub-regions that the tile has been divided into for fragment tracking purposes, fragments generated by the rasterisation stage fall within is determined. Then, for at least one sub-region of the plurality of sub-regions that the tile has been divided into, the processing of fragments for the sub-region of the tile is tracked to determine when the processing of all fragments for the sub-region of the tile has been finished. The writing of rendered fragment data for the sub-region of the tile from the tile buffer to memory is controlled on the basis of the tracking of the processing of fragments for the sub-region of the tile.

  • Patent number: 11361400
    Abstract: A primitive that triggers performance of a graphics operation for the entirety of a tile is included in the sequence of primitives for a sequence of rendering tiles being provided to subsequent stages of the graphics processing pipeline for processing at least one tile in advance of the tile to which the primitive that is to trigger a graphics processing operation for the entirety of the tile relates. If, subsequent to the starting of the processing of the primitive that performs a processing operation for the entirety of the tile, it is determined that no other primitives will be processed for the tile, at least one of the subsequent processing stages of the graphics processing pipeline is caused to stop performing processing in respect of the primitive that performs a processing operation for the entirety of the tile.

  • Patent number: 11321803
    Abstract: A method of operating a tile-based graphics processor that can use one of plural different rendering tile sizes is disclosed. The tile-based graphics processor includes a rasteriser that can rasterise primitives in a hierarchical manner. A patch size at which to begin the hierarchical testing of primitives in the rasteriser is selected based on the rendering tile size that is to be used. This can reduce the overall number of tests performed to rasterise primitives without impacting the correct functioning of the hierarchical rasterisation process.

  • Patent number: 11250611
    Abstract: A method of operating a graphics processor that executes a graphics processing pipeline that can generate a render output using different shading rates is disclosed. First and second input shading rates are combined prior to rasterisation, and a combined shading rate may be propagated through the pipeline instead of the first and second input shading rates. The combined shading rate may then be combined with a third input shading rate at or after the rasterisation stage. This can reduce bandwidth, hardware and energy requirements.

  • Patent number: 10937233
    Abstract: Disclosed herein is a bounding box that can be generated for a set of one or more primitive(s) and then passed to a rasteriser circuit for use thereby when generating the graphics fragments to be processed. The bounding box generation integrates a scissor test and allows primitives for which an initial bounding box has zero intersection with a specified scissor box to be discarded, whereas for primitives whose initial bounding box does intersect the scissor box, a new bounding box can be generated for output based on the area of intersection.
