  • OVERSUBSCRIPTION SCHEDULING
    Publication number: 20220195434
    Abstract: A system for adjusting oversubscription loading includes an interface and a processor. The interface is configured to receive a set of performance data from a set of worker systems. The processor is configured to determine a feedback indication for a worker system of the set of worker systems based at least in part on the set of performance data. The feedback indication is used to adjust an oversubscription controller on the worker system. The processor is configured to provide the feedback indication to the worker system.
    Type: Application

  • Low power programmable image processor
    Patent number: 9477999
    Abstract: A convolution image processor includes a load and store unit, a shift register unit, and a mapping unit. The load and store unit is configured to load and store image pixel data and allow for unaligned access of the image pixel data. The shift register is configured to load and store at least a portion of the image pixel data from the load and store unit and concurrently provide access to each image pixel value in the portion of the image pixel data. The mapping unit is configured to generate a number of shifted versions of image pixel data and corresponding stencil data from the portion of the image pixel data, and concurrently perform one or more operations on each image pixel value in the shifted versions of the portion of the image pixel data and a corresponding stencil value in the corresponding stencil data.
