    摘要： A system-on-chip (SoC) having a switchable power domain capable of being placed in a standby mode during which a power supply of the switchable power domain is gated and having an always-on power domain. The always-on power domain includes an input sampling circuit, and the switchable power domain includes an input/output (IO) circuit configured to, during normal operation, receive data at a corresponding signal pin when an input buffer of the IO circuit is enabled, in which the corresponding signal pin is coupled to the input sampling circuit. The input sampling circuit is configured to, while the switchable power domain is entering the standby mode but before the power supply is gated, provide an override input enable signal to enable the input buffer of the IO circuit, sample an input bit value on the corresponding signal pin, and store the sampled bit value to provide an injection current fault indicator.

    摘要： Aspects extend to methods, systems, and computer program products for balancing input phases across server rack power supplies. A rack manager can monitor individual Alternating Current (AC) phase currents at the rack level. The rack manager knows (or can at least determine) which power supplies are connected to which phase. The rack manager can micro adjust individual PSU output voltages to balance current phases at the rack level. Balancing can occur in response to changed server workloads, hot-unplug of one or more servers, etc. When there is one PSU per server, phase balancing can be accomplished by connecting outputs of power supplies together via busbar or wire. Output voltages of individual power supplies can be adjusted to achieve better phase balancing. Phase imbalance can be corrected by a bus bar or wire carrying enough load to correct phase imbalance.

    摘要： Briefly, system and method for message-based power management which may be used, for example, in computer systems and communications networks. Embodiments of the present invention may include, for example, a device connected to a power management controller (PMC); the device and/or the PMC may send, receive, and/or process power management event (PME) messages. Embodiments of the present invention may operate using links in communicative and/or non-communicative modes. Embodiments of the present invention may include a switch, to send/receive, process, create, re-format and/or route one or more PME message on behalf of various devices, for example, a Peripheral Component Interconnect (PCI) device.

    摘要： An electronic device is provided with at least one functional unit (HB) performing a processing, wherein the functional unit (HB) receives a supply current (Isupply). A supply current monitor (SCM) is provided for monitoring the supply current (Isupply) to determine an average supply current (Iavg). A characterization unit (CU) is provided for determining a first relation between the averaged supply current (Iavg) and an operation frequency of the functional unit and/or for determining a second relation between a workload of the functional unit (HB) and the average supply current (Iavg) of the functional unit (HB). Furthermore, a slope calculation unit (SCU) is provided for determining the slope of the first and/or second relation. The operation of the functional unit (HB) is controlled according to the results of the slope calculation unit (SCU).
