  • Patent number: 11360504
    Abstract: A processor adjusts the voltage margin of a supply voltage based on a sampled clock frequency. The processor generates the supply voltage by combining the voltage margin with a specified nominal voltage, and provides the supply voltage to a processor module, such as graphics processing unit (GPU). In addition, an adaptive clock module (e.g., a digital frequency-locked loop) generates a clock signal for the processor module, wherein the frequency of the clock signal varies at least in part based on the supply voltage. The processor samples the frequency of the clock signal and adjusts the voltage margin based on the sampled frequency. The processor thereby keeps excursions in the clock frequency within a specified limit, thus supporting a relatively stable clock frequency.

  • Patent number: 11360541
    Abstract: A data processor includes at least one power supply voltage terminal for receiving a power supply voltage and a power supply current, a data processing circuit, a register, and a port controller. The data processing circuit is coupled to the at least one power supply voltage terminal and operates using the power supply voltage. The register stores a nominal value of the power supply voltage, an electrical design current (EDC) limit, and an EDC slope, wherein the EDC slope specifies a desired voltage-current relationship for an external voltage regulator when the power supply current exceeds the EDC limit. The port controller is coupled to the register and to an output port. The data processing circuit is operative to cause the port controller to output the nominal value of the power supply voltage, the EDC limit, and the EDC slope over the output port for use by the external voltage regulator.

  • Patent number: 11294448
    Abstract: Mobile devices, such as smartphones, are severely battery-limited. The capabilities of mobile device processors have increased at exponential rates, but battery technologies have improved at much slower rates. As a consequence, it is ever more important that mobile devices be operated in battery-preserving manners. An aspect of the present technology concerns methods and arrangements enabling on-going recognition-processing of imagery and audio by different detectors, without the high battery drain that has characterized the prior art. A variety of other features and arrangements are also detailed.

  • Patent number: 11249536
    Abstract: Reducing power consumption of communication interfaces by clock frequency scaling and adaptive interleaving of polling is disclosed. In a first aspect, a control system controls transmission of a command via a serial interface at a higher clock frequency. After transmission, the control system and the interface are operated at a lower clock frequency to save power during command execution. In this aspect, a reduction in polling corresponds to the reduction in clock signal frequency. When the command is complete, the interface is operated at the higher frequency to send another command. In a second aspect, after the control system sends a command to the receiving device, polling is suspended and an execution time of the command is tracked. Polling begins when the tracked execution time almost equals an expected completion time. Both aspects disclosed above may be implemented to reduce power consumption in exchange for a small increase in latency.

  • Patent number: 11093259
    Abstract: Examples provide for automatically provisioning hosts in a cloud environment. A cloud daemon generates a cloud host-state configuration, for a given cloud instance of a host, stored on a cloud metadata service prior to first boot of the given cloud instance of the host. A first boot of a plurality of cloud instances of hosts is performed using a stateless, master boot image lacking host-specific configuration data. On completion of the first boot of a given cloud instance of a host, the cloud host-state configuration is installed on the master boot image to generate a self-configured boot image including host-specific configuration data for the given cloud instance of the host. A second boot is performed on the given cloud instance of the host by executing the self-configured boot image to automatically provision the given cloud instance of the host in the cloud environment.
