Abstract: A graphics processing system groups plural initial pilot shader programs into a set of initial pilot shader programs and associates the set of initial pilot shader programs with a set of indexes. The initial pilot shader programs each contain constant program expressions to be executed on behalf of an original shader program. The index for an initial pilot shader program is then used to obtain the instructions contained in the initial pilot shader program for executing the constant program expressions of the initial pilot shader program. The threads for executing a subset of the initial pilot shader programs are also grouped into a thread group and the threads of the thread group are executed in parallel. The graphics processing system provides for efficient preparation and execution of plural initial pilot shader programs.

Abstract: A graphics processing pipeline includes processing circuitry. The processing circuitry is configured to determine attribute information for an object to be rendered for a set of sampling points from a compressed representation of attribute information associated with the object, when the set of sampling points is being processed by the graphics processing pipeline to generate a render output. The processing circuitry is also configured to use the determined attribute information to control the processing of the set of sampling points by the graphics processing pipeline when generating the render output.

Abstract: Techniques for performing clipping of graphics primitives 60 with respect to a clipping boundary 65 are described. The clipping step 10 may be performed separately for each tile of a graphics frame to be rendered, after a primitive list for the tile has been read from a primitive memory 38. Clipping may be performed only for larger primitives whose size exceeds a given threshold. Clipping of a primitive 60 to the clipping boundary 65 may be performed inexactly so that only a single clipped primitive is generated which may extend beyond the clipping boundary. A clipped primitive generated by clipping may be used for a depth function calculation of a primitive setup operation and not for an edge determination.

Abstract: In a graphics processing system, a driver for the graphics processing pipeline can include conditional graphics processing tasks in the graphics processing tasks that are to be executed by the graphics processing pipeline to generate a render output required by an application. Each such conditional task has associated with it a condition to be used by the graphics processing pipeline to determine whether to execute processing for the task or not and a region of the render output over which the processing for the task will be executed when the condition for the task is met. The graphics processing pipeline determines whether the condition associated with the task has been met, and only executes the processing for the task if the condition associated with the task has been met.

Abstract: A data processing apparatus comprises processing circuitry arranged to process processing threads using resources accessible to the processing circuitry. A pipeline is provided for handling at least two pending threads awaiting processing by the processing circuitry. The pipeline includes at least one resource-requesting pipeline stage for requesting access to resources for the pending threads. A priority controller controls priority levels of the pending threads. The priority levels define a priority with which pending threads are granted access to resources. When a pending thread reaches a final pipeline stage, if the request resources are not yet available then the priority level of that thread is raised selectively and the thread is returned to a first pipeline stage of the pipeline. If the requested resources are available then the thread is forwarded from the pipeline.
