  • Patent number: 11971740
    Abstract: An integrated circuit and method of designing an integrated circuit including an error detection and correction circuit is described. The integrated circuit includes a data-path being arranged between an output of a first register and second register clocked by a system clock. The integrated circuit includes a timing error detection and correction circuit (EDAC) which has a clock unit configured to receive a reference clock and to provide a delayed reference clock. The EDAC includes a plurality of transition detectors coupled to a respective node on the data-path and an error detection circuit coupled to each transition detector. The error detection circuit flags an error if a transition occurs during a time period between a transition of the reference clock and a corresponding transition of the delayed reference clock. A timing correction circuit coupled to the error detection circuit outputs the system clock derived from the delayed reference clock.

  • Patent number: 11971447
    Abstract: A self-test mechanism within an integrated circuit to automatically interleave evaluation of a clock signal by a clock monitor unit with periodic testing for faulty operation of a clock monitor unit implemented within the integrated circuit for monitoring a clock signal. The mechanism injects faults into the clock monitor unit to evaluate if the clock monitor unit is operating in accordance with its specified operating parameters. The injected faults are intended to cause the clock monitor unit to determine that the clock signal is operating outside of a specified frequency range. If the injected faults do not cause the clock monitor unit to determine that the clock signal is operating both above and below the specified frequency range, then the clock monitor unit is not functioning according to specified operating parameters.

  • Patent number: 11967967
    Abstract: A circuit that receives a series a digital signal values from a digital circuit output where the output has a propensity to produce digital values with a metastable error. The circuit produces an analog output signal having values over time corresponding to the digital signal values. The circuit includes two data paths that receive the digital signal values and produce a delayed analog signal. One data path includes an analog delay and the other data path includes a digital delay and a digital to analog converter. The circuit uses the output of the two data paths to adjust a later output analog signal value that is produced by the analog circuit output subsequent to a former output analog signal value produced by the analog circuit output that corresponds to a digital signal value of the series with a metastable error to compensate for the metastable error in the output signal.

  • Patent number: 11961314
    Abstract: A method is described for analyzing an output of an object detector for a selected object of interest in an image. The object of interest in a first image is selected. A user of the object detector draws a bounding box around the object of interest. A first inference operation is run on the first image using the object detector, and in response, the object detect provides a plurality of proposals. A non-max suppression (NMS) algorithm is run on the plurality of proposals, including the proposal having the object of interest. A classifier and bounding box regressor are run on each proposal of the plurality of proposals and results are outputted. The outputted results are then analyzed. The method can provide insight into why an object detector returns the results that it does.
