Publication number: 20250044844Abstract: Techniques are disclosed relating to selective rate limiting and reducing clock frequency of fabric circuitry in response to certain power management events. Disclosed techniques may advantageously allow power management circuitry to reduce or avoid negative impacts of power events by reducing the clock frequency of a communication fabric while using rate limiting of relatively lower-priority traffic to reduce impacts of the frequency reduction on high-priority traffic. For example, rate limiting of lower-quality-of-service virtual channels may continue after recovery of the clock frequency until higher-quality-of-service virtual channels have recovered from the frequency reduction.Type: ApplicationFiled: August 4, 2023Publication date: February 6, 2025Inventors: Doron Rajwan, Alexander Gendler, Daniel U.

Patent number: 12124314Abstract: An adaptive or dynamic power virus control scheme (hardware and/or software) that dynamically adjusts maximum dynamic capacitance (CdynMax) and corresponding maximum frequency (P0nMax) setting per application executed on a processor core. A power management unit monitors telemetry such as a number of throttled cycles due to CdynMax threshold excursions cycles for the processor core and a cost of average cycle Cdyn cost for the processor core. As the number of throttling cycles increases for the processor core, the aCode firmware of the power management unit decides to increase the Cdyn level or threshold for that core (e.g., to make the threshold less aggressive). As the average Cdyn cost over a number of cycles becomes lower than a threshold, aCode adjusts the threshold to a lower threshold (e.g., more aggressive threshold) and lower Cdyn.Type: GrantFiled: March 19, 2021Date of Patent: October 22, 2024Assignee: Intel CorporationInventors: Alexander Gendler, Adwait Purandare, Ankush Varma, Nazar Haider, Daniela Kaufman, Gilad Bomstein, Shlomo Attias, Amit Gabai, Ariel Szapiro

Publication number: 20240085973Abstract: An apparatus and method are described, which prior to an event that could result in frequency overshoot, sends a signal to a voltage regulator or generator requesting a temporary supply voltage and/or current boost. This enables a clocking source, such as a phase locked loop (PLL) to lock fast while not needing any long-term voltage guard bands. The apparatus and scheme allows for on-the-fly change in supply voltage and/or clock frequency for a processor with little to no impact on Vmin. During the clock frequency overshoot, the supply voltage is temporarily boosted and then reduced down to the expected voltage level of the power supply. Such boost allows for absorbing the clock frequency overshoot impact. The supply voltage level can be reduced in a step-wise fashion to avoid any potential undershoot in clock frequency.Type: ApplicationFiled: November 20, 2023Publication date: March 14, 2024Inventors: Praveen MOSALIKANTI, Nasser A. KURD, Alexander GENDLER

Patent number: 11275663Abstract: A dedicated pin of a processor or system-on-chip (SoC) is used to indicate whether power level (e.g., charge, voltage, and/or current) of a battery falls below a threshold. The threshold can be predetermined or programmable. The battery is used to provide power to the processor and/or SoC. Upon determining that the power level of the battery falls below the threshold, the processor by-passes the conventional process of entering low performance or power mode, and directly throttles voltage and/or operating frequency of the processor. This allows the processor to continue to operate at low battery power. The fast transition (e.g., approximately 10 ?S) from an active state to a low performance or power mode, in accordance with a logic level of the voltage on the dedicated pin, reduces decoupling capacitor design requirements, and makes it possible for the processor to adapt higher package power control settings (e.g., PL4).Type: GrantFiled: June 8, 2020Date of Patent: March 15, 2022Assignee: Intel CorporationInventors: Alexander Gendler, Nimrod Angel, Ameya Ambardekar, Sapumal Wijeratne, Vikas Vij, Tod Schiff, Alexander Uan-Zo-Li
