  • Patent number: 12079920
    Abstract: A graphics processing unit (GPU) includes one or more processor cores adapted to execute a software-implemented shader program, and one or more hardware-implemented ray tracing units (RTU) adapted to traverse an acceleration structure to calculate intersections of rays with bounding volumes and graphics primitives asynchronously with shader operation. The RTU implements traversal logic to traverse the acceleration structure including transformation of rays as needed to account for variations in coordinate space between levels, stack management, and other tasks to relieve burden on the shader, communicating intersections to the shader which then calculates whether the intersection hit a transparent or opaque portion of the object intersected. Thus, one or more processing cores within the GPU perform accelerated ray tracing by offloading aspects of processing to the RTU, which traverses the acceleration structure within which the 3D environment is represented.

  • Patent number: 11907105
    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: 11853763
    Abstract: A new device executing an application on a new central processing unit (CPU), determines whether the application is for a legacy device having a legacy CPU. When the new device determines that the application is for the legacy device, it executes the application on the new CPU with selected available resources of the new device restricted to approximate or match a processing behavior of the legacy CPU, e.g., by reducing a usable portion of a return address stack of the new CPU and thereby reducing a number of calls and associated returns that can be tracked.

  • Patent number: 11847476
    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.

  • Patent number: 11829197
    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.

  • Patent number: 11748840
    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: 20220261945
    Abstract: A data processing system includes a GPU and a switching instruction section. The GPU performs in a time-divided manner a process of generating a plurality of pieces of data corresponding to a plurality of applications executed in parallel. In the case where the GPU completes a process of generating one unit of data that is data corresponding to a first application and that is to be handed over to subsequent processing sections, the switching instruction section instructs the GPU to switch to a process of generating an image corresponding to a second application different from the first application.
