  • Publication number: 20220300324
    Abstract: A multi-processor system performs thermal-aware task scheduling and task migration. Based on temperature measurements, the system determines one or more thermal conditions of each processor. The thermal conditions include a present temperature, a historical temperature, a predicted temperature, and thermal headroom of the processor. A scheduler identifies a target processor among the processors based on, at least in part, the one or more thermal conditions of each processor, and assigns a task to be executed by the target processor. For task migration, the system detects that a source processor satisfies a task migration criterion by comparing one or more of the thermal conditions of the source processor with corresponding thresholds. The scheduler identifies a target processor based on, at least in part, one or more of the thermal conditions of each processor, and migrates a task from the source processor to the target processor for execution.

  • Publication number: 20220138939
    Abstract: Systems and methods for digital pathology in accordance with embodiments of the invention obtain a whole slide image of a microscope slide that includes a registration mark, wherein the registration mark is associated with a coordinate system. The method inputs the whole slide image into a region identification (RI) model to extract features of the whole slide image and generate feature vectors for the extracted features, detects a presence of a region of interest (ROI) based on the feature vectors, determines a set of coordinates of the ROI in the coordinate system, and translates a microscope stage of a microscope holding the microscope slide to a position corresponding to the coordinates of the ROI. The method captures a field of view (FOV) image with the microscope and inputs the FOV image into a grading model to determine a pathology score that indicates a likelihood of a presence of a disease.

  • Patent number: 11138037
    Abstract: A multi-processor system includes multiple processors arranged in multiple clusters. Different clusters have different power and performance characteristics. The system includes a task scheduler to schedule tasks to the processors. The task scheduler, in response to detection of a scheduling event trigger, is operative to identify a scheduling objective between a first objective of energy optimization and a second objective of load balance. The scheduling objective is identified based on at least respective operating frequencies and loading of all processors in a highest-capacity cluster of the multiple clusters. According to the identified scheduling objective, the task scheduler schedules a given task to a processor selected among the processors in the multiple clusters.

  • Patent number: 10862516
    Abstract: A digital pre-distortion circuit and a digital pre-distortion method are provided. In the method, pre-distortion, digital-to-analog conversion and an amplifying process are performed on an input signal in sequence, to generate an output signal. A first bandwidth of the input signal after the pre-distortion is greater than a second bandwidth of the input signal after the digital-to-analog conversion. Signals outside the second bandwidth are filtered out from the output signal, to generate a second output signal. A third output signal, which is a signal after a pre-distorted signal is amplified, is estimated according to the pre-distorted signal and the second output signal. The pre-distorted signal is a signal after the pre-distortion is performed on the input signal. A third bandwidth of the third output signal is greater than the second bandwidth. Parameters of the pre-distortion can be determined according to the third output signal and the pre-distorted signal.
