  • Patent number: 11029747
    Abstract: The time required for transition from an on-state to a suspend state is reduced. An electronic apparatus includes: a memory and a memory; a current control unit that performs a control to shut off supply of current to the memory; and a memory management unit that allocates a memory region in either the memory or the memory based on preference information indicating a memory region that needs to be preferentially allocated in the memory. For example, the preference information includes association with a first priority as a degree at which a memory region to be used by an application needs to be preferentially allocated in the memory, and when receiving a request of allocation of the memory region from the application, the memory management unit more preferentially allocates the memory region in the memory as the first priority associated with the application in the preference information is higher.

  • Patent number: 11016516
    Abstract: Energy packet switches (EPS) employing supercapacitors as storage provide aggregation and delivery of energy to users based on shared-capacitance in a digital power grid. The EPS aggregates energy from one or multiple energy sources, stores and dispatches the energy in discrete amounts as energy packets to one or multiple users. The payload of the energy packet is adjusted by the voltages of the supercapacitors which are used as energy containers for both the EPS and the users. The EPS has a control plane where data transmitted is used to control the operation of the EPS, and a power plane to receive and transmit energy between ports. The power and data planes work in parallel and with a parallel data network. Control and management of the EPS are based on a request-grant transport protocol. The data network is used to receive energy requests and grants, and a granting scheme is used to select which loads are granted energy.

  • Patent number: 11009928
    Abstract: Techniques for optimizing airflow in a network device are provided. In one set of embodiments, a network device can identify one or more device components whose temperature thresholds may be adjusted to be higher (or in other words, more aggressive) than their normal values. The network device can then increase the temperature thresholds for those identified components and use the increased thresholds as static inputs to a fan control algorithm of the device. In another set of embodiments, the network device can check the current airflow within the device on a periodic basis. If the current airflow does not meet an airflow requirement, the network device can incrementally increase the temperature thresholds of the identified components, provide the increased thresholds to its fan control algorithm, and subsequently re-check the current airflow. These steps can repeat until the current airflow meets the airflow requirement.

  • Patent number: 11009934
    Abstract: To eliminate the adverse effects of power swings in a large scale computing system during the life cycle of an application or job, control of several operating characteristics for the collective group of processors is provided. By providing certain levels of coordination for the many processors utilized in large scale computing systems, significant and abrupt changes in power needs can be avoided. In certain circumstances, this may involve limiting the transition between several C-States of the processors involved and the overall power transitions for a large scale system are not detrimental and do not create issues for the data center or local power utility. Some cases will require stepped transitions between C-States, while other cases will include both stepped and modulated transitions. Other cases will incorporate random wait times at the various transitions in order to spread the power consumption involved.

  • Patent number: 10990453
    Abstract: A memory fence or other similar operation is executed with reduced latency. An early fence operation is executed and acts as a hint to the processor executing the thread that executes the fence. This hint causes the processor to begin performing sub-operations for the fence earlier than if no such hint were executed. Examples of sub-operations for the fence include operations to make data written to by writes prior to the fence operation available to other threads. A resolving fence, which occurs after the early fence, performs the remaining sub-operations for the fence. By triggering some or all of the sub-operations for a memory fence that will occur in the future, the early fence operation reduces the amount of latency associated with that memory fence operation.

  • Patent number: 10969849
    Abstract: A method and apparatus for implementing power modes in microcontrollers (MCUs) using power profiles. In one embodiment of the method, a central processing unit (CPU) of the MCU executes a first instruction for calling a subroutine stored in a memory of the MCU, wherein the first instruction comprises a first parameter to be passed to the subroutine. Thereafter the CPU writes a first value to a first special function register (SFR) of the MCU in response to executing the first instruction, wherein the first value is related to the first parameter. The MCU operates in a first power mode in response to the CPU writing the first value to the first SFR. The CPU also executes a second instruction for calling the subroutine, wherein the second instruction comprises a second parameter to be passed to the subroutine. In response the CPU writes a second value to a second SFR of the MCU in response to executing the second instruction, wherein the second value is related to the second parameter.

  • Patent number: 10970185
    Abstract: Systems and methods are disclosed for advising a user when an energy storage device in a computing system needs charging. State of charge data of the energy storage device can be measured and stored at regular intervals. The historic state of charge data can be queried over a plurality of intervals and a state of charge curve generated that is representative of a user's charging habits over time. The state of charge curve can be used to generate a rate of charge histogram and an acceleration of charge histogram. These can be used to predict when a user will charge next, and whether the energy storage device will have an amount of energy below a predetermined threshold amount before the next predicted charging time. A first device can determine when a second device typically charges and whether the energy storage device in the second device will have an amount of energy below the predetermined threshold amount before the next predicted charge time for the second device.

  • Patent number: 10955893
    Abstract: In an embodiment, an integrated circuit includes multiple instances of a component (e.g. a processor) and a control circuit. The instances may be configured to operate in various modes. Some of the modes are incapable of presenting a worst-case load on the power supply. The control circuit may be configured to monitor the instances and detect the modes in which the instances are operating. Based on the monitoring, the control circuit may request to recover a portion of the voltage margin established for worst-case conditions in the instances. If the instances are to change modes, they may be configured to request mode change from the control circuit. If the mode change causes an increase in the current supply voltage magnitude (e.g. to restore some of the recovered voltage margin), the control circuit may cause the restore and permit it to complete prior to granting the mode change.
