  • Power management based on limiting hardware-forced power control
    Patent number: 11853140
    Abstract: Various techniques and circuit implementations for power reduction management in integrated circuits are disclosed. Specifically, a power manager circuit in an integrated circuit (e.g., a system on a chip) may modify power budgets for various components in the integrated circuit to reduce the amount of power control caused by external signaling that indicates a voltage regulator overload (e.g., a voltage droop).
    Type: Grant
    Filed: February 21, 2022
    Date of Patent: December 26, 2023
    Assignee: Apple Inc.
    Inventors: Doron Rajwan, Karl Daniel Wulcan, Tal Kuzi, Inder M. Sodhi, Achmed R. Zahir
  • Telemetry push aggregation
    Patent number: 11822411
    Abstract: Systems, apparatuses, and methods for implementing telemetry push aggregation techniques are described. A computing system includes one or more input/output (I/O) agents interposed between functional units and a communication fabric. A given I/O agent receives a set of aggregation rules from a power management unit. The I/O agent monitors traffic from the functional units, and the I/O agent generates telemetry data from the traffic data based on the set of aggregation rules. The telemetry data is used by the power management unit to make adjustments to one or more power settings.
