Patent number: 11650645Abstract: Power management includes receiving power supply unit (PSU) power capacity data and PSU power consumption data from each PSU in a set of PSUs. A priority table is updated with controlled device power consumption data received from a set of controlled devices. If the PSU power consumption data of any PSU exceeds an associated threshold calculated based on the PSU power capacity data for the PSU, then one or more controlled devices are selected based on the controlled device power consumption data in the priority table. When power consumption data of any PSU exceeds the associated threshold, a power response procedure powers off at least one of the selected one or more controlled devices, reduces power supplied to at least one of the selected one or more controlled devices, or reduces an output voltage of any of the PSU for which the PSU power consumption data exceeds the associated threshold.Type: GrantFiled: July 2, 2021Date of Patent: May 16, 2023Assignee: Arista Networks, Inc.Inventors: Charles Melvin Aden, Eudean Michael Sun

Patent number: 6771556Abstract: The present relief module equipped random access memory avoids the need for enforced idle cycles for the processors, thereby enabling the State Machine to operate at its maximum speed. This relief module equipped random access memory also enables the Central Processing Unit to access the data in the single-port Random Access Memory as required to read and write the data contained therein. This is accomplished by the addition of a single-port Random Access Memory module to the plurality of Random Access Memory modules that are typically specified for a particular application. The extra Random Access Memory module alternates its output with each of the others of the plurality of Random Access Memory modules, on a sequential basis, thereby providing effectively extra clock cycles for each Random Access Memory module.Type: GrantFiled: March 13, 2002Date of Patent: August 3, 2004Assignee: Lucent Technologies Inc.Inventor: Charles Melvin Aden
