  • Publication number: 20200394039
    Abstract: In an embodiment, a processor includes a load/store unit that executes load/store operations. The load/store unit may implement a two-level load queue. One of the load queues, referred to as a load retirement queue (LRQ), may track load operations from initial execution to retirement. Ordering constraints may be enforced using the LRQ. The other load queue, referred to as a load execution queue (LEQ), may track loads from initial execution to forwarding of data. Replay may be managed by the LEQ. In an embodiment, the LEQ may be smaller than the LRQ, which may permit the management of replay while still meeting timing requirements. Additionally, the larger LRQ may permit more load operations to be pending (not retired) in the processor, widening the window for out of order execution and supporting potentially higher processor performance.

  • Publication number: 20200259976
    Abstract: A method of calibrating a vehicular trailering assist system includes hitching a trailer to a vehicle having a rearward viewing camera. Frames of image data are captured by the camera when the vehicle is towing the trailer hitched to the vehicle to determine presence of the trailer and to determine if the particular trailer is a trailer for which the system is calibrated. Responsive to determination that the particular trailer is not a trailer for which the system is calibrated, the system assigns an initial trailer beam length before starting a calibration drive and collects data during the calibration drive. The system iteratively estimates the trailer beam length and, when the predicted trailer angle least deviates from the current determined trailer angle during the calibration drive, the system determines a final estimated trailer beam length for use by the vehicular trailering assist system in determining trailer angles.

  • Publication number: 20200250317
    Abstract: Techniques and apparatuses are described for a cybersecurity risk management tool to assess cybersecurity risk and prioritize cybersecurity correction plans. The cybersecurity risk management tool categorizes cybersecurity framework security controls into maturity indicator levels, identifies implementation states achieved by an entity with respect to the cybersecurity framework security controls, and determines which of the maturity indicator levels represents the implementation state achieved by the entity with respect to each of the cybersecurity framework security controls. A cost-benefit analysis for modifying from the implementation state achieved by the entity to a next implementation state to be achieved by the entity with respect to the cybersecurity framework security controls is also enabled. The cost-benefit analysis leverages factored weights including aspects indicative of security perspectives, Gaussian distributions, and the maturity indicator levels.
