Abstract: A method and graphics processing unit (GPU) are provided for applying texture processing to a block of fragments, each of the fragments being associated with a texture coordinate for each of a plurality of dimensions of a texture. A fragment processing unit of the GPU detects that the texture coordinates for the fragments of the block are axis-aligned, and in response to detecting that the texture coordinates for the fragments of the block are axis-aligned, sends a reduced set of texture coordinates to a texture processing unit of the GPU. The texture processing unit: (i) processes the reduced set of texture coordinates to generate texel addresses of texels to be fetched, (ii) fetches texels using the generated texel addresses, (iii) determines a processed value for each of the fragments of the block based on the fetched texels, and (iv) outputs the processed values.

Abstract: Incompatible graphics frameworks present a barrier to emulating applications of one operating system (guest OS) upon a computer system employing a different operating system (host OS) such as occurs with virtual machines. Accordingly, in order to address limitations of emulating guest OS graphic pipelines upon the host OS the inventors have established methodologies for cross-platform graphics pipeline emulation, thus enabling efficient implementations of cross-platform virtualization solutions, through the establishment of emulation keys to support generic and specific graphics pipelines together with caching sets of graphical pipelines for subsequent retrieval and execution.

Abstract: Apparatus and methods disclosed herein provide an optimal viewpoint from which a virtual camera views a scene in an environment surrounding an ego vehicle. A first value is determined indicating an extent to which a first view from a default viewpoint of the virtual camera satisfies first and second view observation objectives. A second value is determined indicating an extent to which a second view from an alternative viewpoint of the virtual camera satisfies the first and second view observation objectives. If the second value exceeds the first value by an amount greater than a specified criterion value, the alternative viewpoint is selected for the virtual camera. If the second value does not exceed the first value by an amount greater than the specified criterion value, the default viewpoint is selected for the virtual camera.

Abstract: A tracked device may be used in an extended reality system in coordination with a tracking device. The tracked device may be ordinarily difficult to track, for example due to changing appearances or relatively small surface areas of unchanging features, as may be the case with an electronic device with a relatively large display surrounded by a thin physical outer boundary. In these cases, the tracked device may periodically present an image to the tracking device that the tracking device stores as an indication to permit tracking of a known, unchanging feature despite the image not being presented continuously on the display of the tracked device. The image may include a static image, designated tracking data overlaid on an image frame otherwise scheduled for presentation, or extracted image features from the image frame otherwise scheduled for presentation. Additional power saving methods and known marker generation methods are also described.

Abstract: A graphics pipeline includes a first shader that generates first wave groups, a shader processor input (SPI) that launches the first wave groups for execution by shaders, and a scan converter that generates second waves for execution on the shaders based on results of processing the first wave groups by the one or more shaders. The first wave groups are selectively throttled based on a comparison of in-flight first wave groups and second waves pending execution on the at least one second shader. A cache holds information that is written to the cache in response to the first wave groups finishing execution on the shaders. Information is read from the cache in response to read requests issued by the second waves. In some cases, the first wave groups are selectively throttled by comparing how many first wave groups are in-flight and how many read requests to the cache are pending.
