摘要： Computer processing unit intra-frame clock and voltage scaling based on graphics application awareness is disclosed. The computer processing unit includes a processor configured to execute a graphics application to generate a graphics image for output to a display. The computer processing unit includes a power management circuit configured to perform clock and voltage scaling (CVS) (i.e., frequency and/or voltage scaling) for the processor. The power management circuit is configured to identify a graphics application dispatched to be executed or being executed by the processor and to set the operating point for the processor based on the identified graphics application. This may allow the processor to operate at a more optimal operating point for performance of graphics and non-graphics applications as opposed to operating each application at a lower operating point due to a graphics application that is more current intensive.

摘要： A graphics processing unit (GPU) of a GPU subsystem of a computing device processes graphics data to produce a plurality of portions of a first image, and to produce a plurality of portions of a second image. The GPU generates a plurality of data integrity check values associated with the plurality of portions of the first image, and a plurality of data integrity check values associated with the plurality of portions of the second image. The GPU determines whether each of the plurality of portions of the second image matches a corresponding portion of the first image. The GPU determines, prior to producing every portion of the second image, whether an operational fault has occurred in the GPU subsystem based at least in part the determination of whether each of the plurality of portions of the second image matches a corresponding portion of the first image.

摘要： The disclosure describes techniques for a self-test of a graphics processing unit (GPU) independent of instructions from another processing device. The GPU may perform the self-test in response to a determination that the GPU enters an idle mode. The self-test may be based on information indicating a safety level, where the safety level indicates how many faults in circuits or memory blocks of the GPU need to be detected.

摘要： This disclosure describes techniques for executing shader programs in a graphics processing unit (GPU). In some examples, the techniques for executing shader programs may include executing, with a shader unit of a graphics processor, a shader program that performs vertex shader processing and that generates multiple output vertices for each input vertex that is received by the shader program. In further examples, the techniques for executing shader programs may include executing a merged vertex/geometry shader program using a non-replicated mode of execution. The non-replicated mode of execution may involve assigning each of a plurality of primitives to one merged vertex/geometry shader program instance per primitive and causing each of the instances to output a plurality of vertices. In additional examples, the techniques for executing shader programs may include techniques for selecting one of a non-replicated mode and a replicated mode for executing a merged vertex/geometry shader program.
