    Abstract: Graphics processing may include implementing a vertex shader and a pixel shader with the GPU. Vertex indices output from a vertex shader may be written to a cache. The vertex indices written to the cache may be accessed with the pixel shader and vertex parameter values associated with the vertex indices may be accessed from a memory unit with the pixel shader. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

    IPC: G06T15/00

    Abstract: A method for graphics processing. The method including rendering graphics for an application using graphics processing units (GPUs). The method including dividing responsibility for processing a plurality of pieces of geometry of an image frame during an analysis pre-pass phase of rendering between the plurality of GPUs, wherein each of the plurality of pieces of geometry is assigned to a corresponding GPU. The method including determining in the analysis pre-pass phase overlap of each the plurality of pieces of geometry with each of a plurality of screen regions. The method including generating information at the plurality of GPUs regarding the plurality of pieces of geometry and their relations to the plurality of screen regions based on the overlap of each the plurality of pieces of geometry with each of the plurality of screen regions. The method including assigning the plurality of screen regions to the plurality of GPUs based on the information for purposes of rendering the plurality of pieces of geometry during a subsequent phase of rendering.

    IPC: G06T1/20

    Abstract: A graphics processing may include implementing a vertex shader and a pixel shader with a GPU. Vertex parameter values may be compressed with the vertex shader and compressed vertex parameter values may be written to a cache. The pixel shader may access the compressed vertex parameter values that were written to the cache and decompress the compressed vertex parameter values.
