Abstract: Approaches in accordance with various embodiments can reduce scheduling delays due to concurrent processing requests, as may involve VSyncs in multi-streaming systems. The software synchronization signals can be staggered relative to each other by offsetting an initial synchronization signal. These software synchronization signals can be readjusted over time such that each synchronization signal maintains the same relative offset, as may be with respect to other applications or containers.

Abstract: A performance metrics of a receiver is obtained using frames of an application hosted by a server that are received via a network. The one or more performance metrics include information indicative of a current occupancy of a frame buffer corresponding to the receiver and information indicative of a target occupancy of the frame buffer corresponding to the receiver. The frame buffer of the receiver is used to queue frames of the application for display. A frame rate associated with rendering at least one next frame of the application is adjusted using the one or more performance metrics of the receiver to control population of the frame buffer. Subsequent frames of the application hosted by the server are rendered using the adjusted frame rate. Upon rendering the subsequent frames, the server sends the subsequent frames to the receiver for display.

Abstract: The subject application relates to computing an authentication tag for partial transfers scheduled across multiple direct memory access (DMA) engines. Apparatuses, systems, and techniques are described for computing an authentication tag for a data transfer when the data transfer is scheduled as partial transfers across a specified number of direct memory access (DMA) engines. An orchestration circuit stores partial authentication tags, computed by the DMA engines, and corresponding adjustment exponents during one or more rounds in which the partial transfers are scheduled and processed by the specified number of DMA engines. During a last round, a combined authentication tag can be computed based on the partial authentication tags and the corresponding adjustment exponents stored by the orchestration circuit during the rounds.

Abstract: An end-to-end system for data generation, map creation using the generated data, and localization to the created map is disclosed. Mapstreams—or streams of sensor data, perception outputs from deep neural networks (DNNs), and/or relative trajectory data—corresponding to any number of drives by any number of vehicles may be generated and uploaded to the cloud. The mapstreams may be used to generate map data—and ultimately a fused high definition (HD) map—that represents data generated over a plurality of drives. When localizing to the fused HD map, individual localization results may be generated based on comparisons of real-time data from a sensor modality to map data corresponding to the same sensor modality. This process may be repeated for any number of sensor modalities and the results may be fused together to determine a final fused localization result.

Abstract: In various examples, a media stream may be received by a re-encode system that may leverage a recode engine to convert (e.g., at an interval, based on a request, etc.) an inter-frame associated with the media stream to an intra-frame. The intra-frame may be converted from the inter-frame using parameters or other information associated with and received with the media stream. The converted intra-frame may be merged into an updated segment of the media stream in place of the original inter-frame to enable storage of the updated segment—or a portion thereof—for later use.

Abstract: In accordance with the disclosure, one or both semiconductor dies in a face-to-face arrangement may include a probe pad layer formed on a face of the die to allow the die to be individually tested prior to assembly of the dies. Thus, faulty dies may be discarded individually so they are not included in a composite semiconductor device, thereby increasing device yields. The probe pad layer also allows dies to be matched so that a composite semiconductor device achieves desired performance, which may further increase device yields. In some embodiments, the probe pads of the probe pad layer formed on the face of the die may be used to individually test the die, and may remain inactive, or inert, during operation of the composite semiconductor device.

Abstract: In various examples, permanent faults in hardware component(s) and/or connections to the hardware component(s) of a computing platform may be predicted before they occur using in-system testing. As a result of this prediction, one or more remedial actions may be determined to enhance the safety of the computing platform (e.g., an autonomous vehicle). A degradation rate of a performance characteristic associated with the hardware component may be determined, detected, and/or computed by monitoring values of performance characteristics over time using fault testing.

Abstract: In various examples, a low-latency variable backlight liquid crystal display (LCD) system is disclosed. The LCD system may reduce latency and video lag by performing an analysis of peak pixel values within subsets of pixels using a rendering device, prior to transmitting the frame to a display device for display. As a result, the display device may receive the peak pixel value data prior to or concurrently with the frame data, and may begin updating the backlight settings of the display without having to wait for a substantial portion of the frame to be received. In this way, the LCD system may avoid the full frame delay of conventional systems, allowing the LCD system to more reliably support high-performance applications such as gaming.

Abstract: In various examples, a voltage monitor may determine whether the voltage supplied to at least one component of a computing system is safe using two sets of thresholds—e.g., a high-frequency over-voltage (OV) threshold, a high-frequency under-voltage (UV) threshold, a low-frequency OV threshold, and a low-frequency UV threshold. A high-frequency voltage error detector may compare the supplied or input voltage to the high-frequency OV and UV thresholds and a low-frequency voltage error detector that may filter the supplied voltage to remove or reduce noise and then may compare the filtered voltage to the low-frequency OV and UV thresholds. Upon detecting a voltage error, a safety monitor may cause a change to an operating state of the at least one component.

Abstract: Embodiments of the present disclosure relate to workload-based dynamic throttling of video processing functions. Systems and methods are disclosed that dynamically throttle video processing and/or streaming based on a workload. Live video is captured from one or more sources (e.g., cameras) and stored. The video is then provided to a video processing engine and a video streaming engine. The video processing engine may perform one or more operations such as object detection, object tracking, and object classification to produce characterization data (e.g., bounding boxes, object trajectories, alerts, object labels, object counts, boundary crossings, intersection highlighting, etc.). System resource usage and performance of the video processing and streaming are monitored to produce workload data (e.g., metrics). Based on the policies and the workload data, the video streaming and/or processing is dynamically reconfigured by adjusting parameters provided to the video streaming and processing engines.

Abstract: In various examples, a background of an object may be modified to generate a training image. A segmentation mask may be generated and used to generate an object image that includes image data representing the object. The object image may be integrated into a different background and used for data augmentation in training a neural network. Data augmentation may also be performed using hue adjustment (e.g., of the object image) and/or rendering three-dimensional capture data that corresponds to the object from selected views. Inference scores may be analyzed to select a background for an image to be included in a training dataset. Backgrounds may be selected and training images may be added to a training dataset iteratively during training (e.g., between epochs). Additionally, early or late fusion nay be employed that uses object mask data to improve inferencing performed by a neural network trained using object mask data.

Abstract: Various approaches are disclosed to temporally and spatially filter noisy image data—generated using one or more ray-tracing effects—in a graphically rendered image. Rather than fully sampling data values using spatial filters, the data values may be sparsely sampled using filter taps within the spatial filters. To account for the sparse sampling, locations of filter taps may be jittered spatially and/or temporally. For filtering efficiency, a size of a spatial filter may be reduced when historical data values are used to temporally filter pixels. Further, data values filtered using a temporal filter may be clamped to avoid ghosting. For further filtering efficiency, a spatial filter may be applied as a separable filter in which the filtering for a filter direction may be performed over multiple iterations using reducing filter widths, decreasing the chance of visual artifacts when the spatial filter does not follow a true Gaussian distribution.
