  • Reducing false positive ray traversal in a bounding volume hierarchy
    Patent number: 12198251
    Abstract: Techniques applicable to a ray tracing hardware accelerator for traversing a hierarchical acceleration structure with reduced false positive ray intersections are disclosed. The reduction of false positives may be based upon one or more of selectively performing a secondary higher precision intersection test for a bounding volume, identifying and culling bounding volumes that degenerate to a point, and parametrically clipping rays that exceed certain configured distance thresholds.

  • Cascaded phase interpolator topology for quadrature-rate multilevel pulse amplitude modulation data sampling
    Patent number: 12199619
    Abstract: A receiver includes a multi-phase clock generator to generate phases of a clock signal and a global phase interpolator (PI) circuit coupled to the multi-phase clock generator and to clock and data recovery (CDR) circuitry. The global PI circuit generates initial-adjusted phases from the phases of the clock signal based on a control signal received from the CDR circuitry. A first local PI receives the initial-adjusted phases of the clock signal and applies a first fixed phase shift to the initial-adjusted phases to generate first final-adjusted phases of the clock signal that are useable to sample a first level of multiple levels of a pulse-amplitude-modulated (PAM) data stream.

  • Query-specific behavioral modification of tree traversal
    Patent number: 12198255
    Abstract: Methods and systems are described in some examples for changing the traversal of an acceleration data structure in a highly dynamic query-specific manner, with each query specifying test parameters, a test opcode and a mapping of test results to actions. In an example ray tracing implementation, traversal of a bounding volume hierarchy by a ray is performed with the default behavior of the traversal being changed in accordance with results of a test performed using the test opcode and test parameters specified in the ray data structure and another test parameter specified in a node of the bounding volume hierarchy. In an example implementation a traversal coprocessor is configured to perform the traversal of the bounding volume hierarchy.

  • Programming model for resource-constrained scheduling
    Patent number: 12197954
    Abstract: The present technology augments the GPU compute model to provide system-provided data marshalling characteristics of graphics pipelining to increase efficiency and reduce overhead. A simple scheduling model based on scalar counters (e.g., semaphores) abstract the availability of hardware resources. Resource releases can be done programmatically, and a system scheduler only needs to track the states of such counters/semaphores to make work launch decisions. Semantics of the counters/semaphores are defined by an application, which can use the counters/semaphores to represent the availability of free space in a memory buffer, the amount of cache pressure induced by the data flow in the network, or the presence of work items to be processed.

  • 3D surface structure estimation using neural networks for autonomous systems and applications
    Patent number: 12190448
    Abstract: In various examples, to support training a deep neural network (DNN) to predict a dense representation of a 3D surface structure of interest, a training dataset is generated using a simulated environment. For example, a simulation may be run to simulate a virtual world or environment, render frames of virtual sensor data (e.g., images), and generate corresponding depth maps and segmentation masks (identifying a component of the simulated environment such as a road). To generate input training data, 3D structure estimation may be performed on a rendered frame to generate a representation of a 3D surface structure of the road. To generate corresponding ground truth training data, a corresponding depth map and segmentation mask may be used to generate a dense representation of the 3D surface structure.
