  • Publication number: 20220004219
    Abstract: An application designed for the current version of a system runs at a standard clock frequency of a current version of the system. Running the application at the standard clock frequency includes synchronizing operation of a processor of the current version of the system with the standard clock frequency. An application designed for a different version of the system characterized by a different standard clock frequency runs at a second clock frequency that is different than the standard clock frequency. Running the application at the second clock frequency includes synchronizing operation of the processor of the current version of the system with the second clock frequency.

  • Publication number: 20210365282
    Abstract: To facilitate backwards compatibility, a computing device may respond to a call from an application for information regarding a processor on the computing device by returning information regarding a different processor than the processor on the computing device, including one or more of processor model, processor family, cache capabilities, translation lookaside buffer capabilities, processor serial number, processor brand, processor manufacturer, thread/core topology, cache topology, extended features, virtual address size, or physical address size that differs when the processor determines that the application is a legacy device application

  • Publication number: 20210334933
    Abstract: Methods for graphics processing are provided. One example method includes executing a plurality of kernels using a plurality of graphics processing units (GPUs), wherein responsibility for executing a corresponding kernel is divided into one or more portions each of which being assigned to a corresponding GPU. The method includes generating a plurality of dependency data at a first kernel as each of a first plurality of portions of the first kernel completes processing. The method includes checking dependency data from one or more portions of the first kernel prior to execution of a portion of a second kernel. The method includes delaying execution of the portion of the second kernel as long as the corresponding dependency data of the first kernel has not been met.

  • Publication number: 20210311856
    Abstract: A device having a Graphics Processing Unit (GPU) may be configured to selectively run in a normal mode or a timing testing mode. In the timing testing mode the device is configured to disrupt timing of processing that takes place on the GPU while running an application with the GPU and test the application for errors in device hardware component and/or software component synchronization while the device is running in the timing testing mode.

  • Patent number: 11119528
    Abstract: An application runs at a first operating frequency if the application is designed for a current version of a system and runs at a second operating frequency if the application is designed for a prior version of the system that operates at a lower frequency than the first operating frequency. The second operating frequency may be higher than the operating frequency of the prior version of the system to account for differences in latency, throughput or other processing characteristics between the two systems. Software readable cycle counters are based on a spoof clock running at the operating frequency of the prior version of the system, rather than the true operating frequency. 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.

  • Publication number: 20210166338
    Abstract: Graphics processing renders a scene with a plurality of different rendering parameters for different locations on a screen area. Each primitive of a batch of primitives belonging to an object covering at least two of the zones of the screen area is assembled to a screen space. Assembling each of the primitives includes iterating each primitive with a primitive assembler for each of the zones covered by the object. Each said zone is associated with a different set of screen space transform parameters used to transform locations of vertices in the batch of primitives from a homogenous coordinate space to a screen space that is not flat. The zones are arranged to minimize an overlap between zones.

  • Publication number: 20210157610
    Abstract: Performance of a legacy application may be characterized for subsequent adjustment of operating parameters when running the legacy application on a newer system. The legacy application is run on an older system and one or more key performance metrics that must be met when the legacy application is run on the newer system are determined along with other performance information useful for later adjustment of operating parameters of the newer system when running the legacy application on the newer system.

  • Patent number: 10915981
    Abstract: Graphics processing renders a scene with a plurality of different rendering parameters for different locations on a screen area. Graphics depicting one or more objects mapped to a screen area are processed. The screen area includes a plurality of zones, each having a different set of rendering parameters. Primitives belonging to one of the objects that covers at least two of the zones are received. Each primitive is assembled to screen space by iterating each primitive over each zone it covers using the rendering parameters of the respective zone with each iteration.

  • Publication number: 20210005008
    Abstract: In a computer graphics processing unit (GPU) having a texture unit, when pixel sample locations are based on a non-orthonormal grid in scene space, the texture unit receives texture space gradient values directly, e.g., from a shader unit or generates them from texture coordinates supplied, e.g., by a shader unit, and then applies a transformation to the gradient values configured to adjust the gradient values to those which would arise from the use of a orthonormal screen space grid.

  • Publication number: 20200302574
    Abstract: In graphics processing data is received representing one or more vertices for a scene in a virtual space. Primitive assembly is performed on the vertices to compute projections of the vertices from virtual space onto a viewport of the scene in a screen space of a display device containing a plurality of pixels, the plurality of pixels being subdivided into a plurality of subsections. Scan conversion determines which pixels of the plurality of pixels are part of each primitive that has been converted to screen space coordinates. Coarse rasterization for each primitive determines which subsection or subsections the primitive overlaps. Metadata associated with the subsection a primitive overlaps determines a pixel resolution for the subsection. The metadata is used in processing pixels for the subsection to generate final pixel values for the viewport of the scene that is displayed on the display device in such a way that parts of the scene in two different subsections have different pixel resolution.
