摘要： Techniques are provided for detecting a fault across a pair of lines. Pulse power is applied across the pair of lines. The pulse power comprises alternating pulse on-time intervals and pulse off-time intervals. During a pulse off-time interval, a resistor is connected across the pair of lines and then disconnected when a voltage across the pair of lines reaches a first droop percentage in a first period of time. After disconnecting the resistor, it is determined whether the voltage across the pair of lines droops at least a second droop percentage within a second period of time that begins after the first period of time. Occurrence of a line-to-line fault across the pair of lines is determined when the voltage across the pair of lines droops by at least the second droop percentage or more within the second period of time.

摘要： Systems and methods for managing the distribution of electrical power are disclosed. The system can maintain a status of each account of a plurality of accounts. Each account can correspond to an electrical power generation device, an electrical power consumption device, and an electrical power transmission device. The system can generate a first record object in response to the generation of a unit of power. The system can identify a first path identifying a source device and a destination device to transmit the unit of power. The system can generate a control signal to route the unit of power from the source device to the destination device. The system can update an event tracker to indicate the routing of the unit of power. The system can generate a second record object corresponding to the destination device.

摘要： A computer-implemented method for detecting n-level slopes for a voltage level in a processor, wherein n is greater than 1, includes monitoring a voltage in a processor for a voltage level corresponding to a predefined first edge, and monitoring for a voltage level corresponding to a predefined second edge within a first count limit from detection of the predefined first edge. In response to detecting the predefined second edge within the first count limit, the computer-implemented method includes monitoring for a voltage level corresponding to a predefined third edge within a second count limit from detection of the predefined second edge, and in response to detecting the predefined third edge within the second count limit, determining whether to adjust a power applied to the processor based on the monitored voltage levels.

摘要： Various embodiments include methods performed by a processor for managing voltage droop margins of a power distribution network (PDN). Various embodiments may include receiving, by a processor from a first client powered by a shared power rail within the PDN, a first requested performance corner, receiving, by the processor from a second client powered by the shared power rail, a second requested performance corner, determining by the processor a first peak current value based on the first requested performance corner, determining by the processor a second peak current value based on the second requested performance corner, determining by the processor a system voltage droop margin based on the first peak current value, the second peak current value, and an impedance value of the PDN, and adjusting a voltage of the shared power rail based on the system voltage droop margin.

摘要： An activity smoothener circuit is provided to control rates of change in processing activity to limit di/dt in activity areas of an IC to mitigate voltage droops or overshoots. Controlling the rate of change of activity prevents or reduces instances of a di/dt exceeding a programmed maximum that is based on physical limits of the IC and/or a package. In examples, the activity smoothener circuit includes a hierarchy of smoothening circuits controlling activity in areas down to individual circuit blocks (tiles) including execution circuits. An indication of a desired level of activity is provided to a parent smoothening circuit and the parent smoothening circuit responds with indications of actual activity allowed to occur. At each level of hierarchy, the activity smoothener circuit may use algorithms to generate indications of actual activity based on indications of desired activity and di/dt limits. Di/dt limits and current minimums and maximums are controlled.
