  • Patent number: 11275663
    Abstract: 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).

  • Patent number: 11119555
    Abstract: In one embodiment, a processor includes a plurality of cores and a power controller. This power controller in turn may include a voltage ramp logic to pre-empt a voltage ramp of a voltage regulator from a first voltage to a second voltage, responsive to a request for a second core to exit a low power state. Other embodiments are described and claimed.

  • Patent number: 10614774
    Abstract: Techniques and mechanisms for an integrated circuit (IC) chip to generate a clock signal for use by one or more resources of the IC chip. In an embodiment, a clock signal is generated with phase-locked loop (PLL) circuitry of an IC chip based on a cyclical signal which is provided to the IC chip by an external source. A supply voltage provided to the PLL circuitry is automatically updated based on one of a requested frequency for the clock signal, a frequency of the received cyclical signal, or a voltage of a control signal used by a voltage controlled oscillator of the PLL circuitry. In another embodiment, a series of incremental changes to a frequency of the clock signal is automatically performed according to a predefined overclocking scheme or underclocking scheme.

  • Patent number: 9501299
    Abstract: A processor may include a cause agnostic frequency dither filter (FD filter), which may cause reduction in the frequency transitions while maintaining the performance levels. The FD Filter may minimize the performance loss, which may otherwise accrue from these frequency transitions, while trying to maximize the peak frequency of the processor. The FD filter may determine a minimum and maximum limit, which may be used by a power management unit (PMU) to restrict the number of frequency transitions to be within a specified threshold. The FD filter may determine the maximum and minimum limits based on transition data stored in internal tables captured during one or more time windows (or observation windows). Based on an average system behavior, the PMU may either apply the minimum or the maximum limit over the subsequent time window.
