  • Patent number: 11061432
    Abstract: A data handoff controller includes a counter coupled to supply a count value indicative of a skew between a first clock signal and a second clock signal. The first and second clock signal have a fundamental beat frequency. A greatest common factor circuit is used to determine the fundamental beat frequency and the second is reset based on the beat frequency. A sampling circuit samples first clock domain data with the second clock signal. The sampling circuit is controlled to sample, at least in part, based on the count value. The count value can be used to impose a blackout window in which data is not sampled to avoid sampling data around data transitions of the first clock domain data. The count value can also be used to select an edge of the second clock signal to use for sampling the first clock domain data to ensure first clock domain data is not sampled during data transitions.

  • Patent number: 11029745
    Abstract: Systems and methods are disclosed method for controlling instantaneous current changes in parallel processors with arrays of parallel computing elements, such as neural processors. An exemplary method comprises monitoring the array of computing elements and determining a transition from a first activity level of the array to a second activity level of the array, such as an idle-to-active or active-to-idle transition. Once a transition is determined, the array is selectively controlled to minimize the instantaneous current change from the transition from the first activity level to the second activity level.

  • Patent number: 10990120
    Abstract: A method operates a first-in-first-out (FIFO) buffer with a first clock, and operates one of a read pointer or a write pointer of the FIFO buffer with the first clock while operating the other one of the read pointer or write pointer with a second clock. One of a serializer fed from the FIFO buffer output, or a de-serializer feeding the FIFO buffer input, is operated with the second clock. Timing pulses indicate that the pointer operating with the second clock has reached a predetermined point in its cycle. The phase of the second clock is adjusted based on a relationship between the timing pulses and an advance period of the pointer operating with the first clock. The pointer operating with the first clock is reset to achieve a desired value for the relationship. A skew created from adjusting the phase of the second clock is corrected.

  • Patent number: 10976791
    Abstract: An access point, which is a Power over Ethernet (PoE) Powered Device (PD) measures input voltage and input current. The access point determines a power requirement of the access point based on the measured current, measured voltage, and information about power requirements of access point components or devices coupled to the access point a power requirement of the access point. The access point communicates the determined power request to a power sourcing equipment (PSE), e.g., a network switch. In some embodiments, the access point further communicates one of: measured input current and measured input voltage to the PSE. The PSE uses the information received from the access point, e.g., power request and power measurements to determine an amount of power to be granted to the access point. If the access point does not receive the requested power level the access point selects internal components and/or external devices to de-power.

  • Patent number: 10956170
    Abstract: A BIOS setting modification system is provided in a computing device. During a computing device runtime for the computing device, an Out-Of-Band (OOB) controller device receives a first BIOS setting modification request and, in response, generates first BIOS setting modification information and causes the transmission of a System Management Interrupt (SMI). During the computing device runtime for the computing device, an SMI handler subsystem in the computing device retrieves, in response to the SMI, the first BIOS setting modification information, either directly from the OOB controller device, or from a storage subsystem in which it was provided by the OOB controller device. The SMI handler subsystem then applies the first BIOS setting modification information to at least one subsystem in the computing device such that a first BIOS setting modification provided by the first BIOS setting modification information takes effect during the computing device runtime for the computing device.

  • Patent number: 10936724
    Abstract: Techniques for configurable compute instance resets are described. A user can issue a request to securely reset one or more compute instances implemented within a service provider system. Each compute instance is reset to a previous point in time, such that any activity of the compute instance or effects thereof occurring since that point in time are completely eliminated. Each compute instance reset can include removing an existing volume of the compute instance, obtaining a volume, attaching the obtained volume to the compute instance, and rebooting the compute instance. Configuration data of the compute instance, such as an instance identifier or network addresses, can be maintained after the reset.

  • Patent number: 10936038
    Abstract: A computing device may comprise a volatile memory and a non-volatile storage device. Upon system shutdown, contents of the volatile memory may be preserved by memory transfer operations from the volatile memory to the non-volatile storage device. During memory preservation, the computing device may enter a low-power state. The low-power state may comprise suspension of power to a core of a processor while maintaining power to the processor's uncore, and disablement of interrupt signals not related to memory transfer operations. Power delivery to the core of the processor may be periodically resumed to initiate additional memory transfer operations.
