  • Patent number: 12045675
    Abstract: Systems, apparatuses, and methods for implementing a safety monitor framework for a safety-critical graphics processing unit (GPU) compute application are disclosed. A system includes a safety-critical GPU compute application, a safety monitor, and a GPU. The safety monitor receives a compute grid, test vectors, and a compute kernel from the safety-critical GPU compute application. The safety monitor generates a modified compute grid by adding extra tiles to the original compute grid, with the extra tiles generated based on the test vectors. The safety monitor provides the modified compute grid and compute kernel to the GPU for processing. The safety monitor determines the likelihood of erroneous processing of the original compute grid by comparing the actual results for the extra tiles with known good results. The safety monitor complements the overall fault coverage of the GPU hardware and covers faults only observable at the application programming interface (API) level.

  • Patent number: 11971803
    Abstract: Systems, apparatuses, and methods for implementing a safety monitor framework for a safety-critical computer vision (CV) application are disclosed. A system includes a safety-critical CV application, a safety monitor, and a CV accelerator engine. The safety monitor receives an input image, test data, and a CV graph from the safety-critical CV application. The safety monitor generates a modified image by adding additional objects outside of the input image. The safety monitor provides the modified image and CV graph to the CV accelerator which processes the modified image and provides outputs to the safety monitor. The safety monitor determines the likelihood of erroneous processing of the original input image by comparing the outputs for the additional objects with a known good result. The safety monitor complements the overall fault coverage of the CV accelerator engine and covers faults only observable at the level of the CV graph.

  • Patent number: 11954792
    Abstract: Systems, apparatuses, and methods for performing real-time video rendering with performance guaranteed power management are disclosed. A system includes at least a software driver, a power management unit, and a plurality of processing elements for performing rendering tasks. The system receives inputs which correspond to rendering tasks which need to be performed. The software driver monitors the inputs that are received and the number of rendering tasks to which they correspond. The software driver also monitors the amount of time remaining until the next video synchronization signal. The software driver determines which performance setting will minimize power consumption while still allowing enough time to finish the rendering tasks for the current frame before the next video synchronization signal. Then, the software driver causes the power management unit to provide this performance setting to the plurality of processing elements as they perform the rendering tasks for the current frame.

  • Publication number: 20210097184
    Abstract: A processing system isolates at a physically or logically separate memory region of a processing unit boot code that is received from an external boot source for programming a boot memory of the processing unit until after the boot code is validated to protect against buffer overruns that could compromise the processing system. The processing unit includes a secure buffer region of memory that is physically or logically isolated from the remainder of the processing unit for receiving boot code from an external boot source such as a personal computer (PC) such that any buffer overruns at the secure buffer simply overwrite data stored at the secure buffer, and do not affect data or instructions that are executing at the processing unit.

  • Patent number: 7996750
    Abstract: A system and method for correcting so-called “lip sync” errors is provided, using a synchronization test signal comprising a video signal including a colorbar signal that is periodically interrupted by a series of consecutive defined black frames and an audio signal comprising a tone periodically interrupted by a period of silence beginning at the same time as the first of the series of consecutive defined black frames. The synchronization test signal is configured to survive encoding, decoding, conversion, and compressing processes used in a typical digital broadcast system environment and thus provide a means of measuring the relative audio and video timing of a processed signal.
