  • Request and Floor Interface for Current Control with Correctness in an SOC
    Publication number: 20250199598
    Abstract: In an embodiment, a system may include a plurality of component circuits. The plurality of component circuits may include rate control circuits the control power consumption in the component circuits based on indications of power allocated to the component circuits. In an embodiment, the rate control circuits may transmit power requests for the component circuits and a floor request representing a minimum amount of power that may ensure reliable operation.
    Type: Application

  • Asymmetrical Power Sharing
    Publication number: 20250103121
    Abstract: Techniques are disclosed relating to managing power allocation for component circuits coupled to one or more power sources. A system can include a first integrated circuit die that is indirectly coupled to a second integrated circuit die through a set of intervening integrated circuit dies. The system can include a first power source configured to supply power to component circuits of the first and second integrated circuit dies. The first integrated circuit may allocate, to a first set of component circuits of the first integrated circuit die, a first set of power credits for obtaining power from the first power source. The first integrated circuit may send a second set of power credits to the second integrated circuit die through the set of intervening integrated circuit dies without the set of intervening integrated circuit dies using the second set of power credits to obtain power from the first power source.
