Latest Patents

One of his latest patents is titled "Real-time low latency computer vision/machine learning compute accelerator with smart convolutional neural network scheduler." This invention provides methods and devices for processing image data on a sub-frame portion basis using layers of a convolutional neural network. The processing device includes memory and a processor, which is configured to receive frames of image data comprising sub-frame portions. The processor schedules a first sub-frame portion of a first frame for processing by the first layer of the convolutional neural network when it becomes available. This method allows for continuous processing as soon as sufficient data is available for each layer.

Another significant patent is the "Safety monitor for image misclassification." This system implements a safety monitor framework for safety-critical inference applications. It includes a safety monitor that receives an input image, test data, and a neural network specification. The safety monitor generates a modified image by adding additional objects outside of the input image. It then provides this modified image to an inference accelerator engine, which processes it and outputs results to the safety monitor. The safety monitor assesses the likelihood of erroneous processing by comparing outputs for the additional objects with known good results, enhancing the overall fault coverage of the inference accelerator engine.
