  • Patent number: 11599185
    Abstract: Energy consumption is reduced within an Internet of Things (IoT) device, without degrading operating performance of the corresponding internal circuitry. A first internal supply voltage (VDDa) used to supply the internal circuitry is reduced from a VDD supply voltage to a lower voltage during an idle state, thereby reducing leakage currents in the internal circuitry. The first internal supply voltage (VDDa) may be reduced to a voltage that is one threshold voltage (Vtp) lower than the VDD supply voltage. A second internal supply voltage (VSSa) used to supply the internal circuitry is increased from the VSS supply voltage to a voltage higher than the VSS supply voltage during the idle state, thereby further reducing leakage currents in the internal circuitry. The second internal supply voltage (VSSa) may be increased to a voltage that is one threshold voltage (Vtn) higher than the VSS supply voltage.

  • Patent number: 11435802
    Abstract: A real-time workload scheduling heuristic assigns tasks to the cores such that the total load current consumption of the cores is always less than the total current capability of the under-provisioned on-chip voltage regulators. In addition, the energy-efficient scheduling of the tasks on to the cores ensures that the reconfiguration of the power delivery network is minimized. The heuristic includes DVFS management based on the unique constraints of the under provisioned voltage regulators.

  • Patent number: 11416265
    Abstract: A method of tuning performance of a data storage system includes calculating an estimate of parallel fraction and speedup characteristic for a data storage application executed by the data storage system. The estimate is calculated using linear regression of values (1/N, 1/XN) that are generated from trial runs of the data storage application processing a workload using respective different numbers N of CPU cores to obtain corresponding performance values XN. The method further includes configuring the data storage system to execute the data storage application using a number of CPU cores based on the estimate of parallel fraction and speedup characteristic.

  • Patent number: 11188141
    Abstract: Circuits, methods, and apparatus that may determine one or more characteristics relating to a mains power supply received by a computer system, and may then determine a maximum amount of power that may be drawn by the computer system given the determined characteristics. An example may provide a computer system having a power supply circuit that may include a detection circuit to receive a mains power supply and to detect a characteristic of the mains power supply. In response to the detected characteristic, the detection circuit may provide an output to a circuit in the computer system that sets a limit on a current that may be drawn by the circuit. In this example, the characteristic may be an RMS value of the mains power supply waveform, a location of where the mains power supply is being received, a quality of the mains power supply, or other characteristic.
