20090158068 | REDUCING CORE WAKE-UP LATENCY IN A COMPUTER SYSTEM - A power control unit (PCU) may reduce the core wake-up latency in a computer system by concurrently waking-up the remaining cores after the first core is woken-up. The power control unit may detect arrival of a first, second, and a third interrupt directed at a first, second, and a third core. The power control unit may check whether the second interrupt occurs within a first period, wherein the first period is counted after waking-up of the first core is complete. The power control unit may then wake-up the second and the third core concurrently if the second interrupt occurs within the first period after the wake-up activity of the first core is complete. The first period may at least equal twice the time required for a first credit to be returned and next credit to be accepted. | 06-18-2009 |

20130332753 | DYNAMIC POWER LIMIT SHARING IN A PLATFORM - A method and apparatus for dynamic power limit sharing among the modules in the platform. In one embodiment of the invention, the platform comprises a processor and memory modules. By expanding the power domain to include the processor and the memory modules, dynamic sharing of the power budget of the platform between the processor and the memory modules is enabled. For low-bandwidth workloads, the dynamic sharing of the power budget offers significant opportunity for the processor to increase its frequency by using the headroom in the memory power and vice versa. This enables higher peak performance for the same total platform power budget in one embodiment of the invention. | 12-12-2013 |

20140195828 | DYNAMICALLY MEASURING POWER CONSUMPTION IN A PROCESSOR - In one embodiment, the present invention includes a processor having multiple cores to independently execute instructions, a first sensor to measure a first power consumption level of the processor based at least in part on events occurring on the cores, and a hybrid logic to combine the first power consumption level and a second power consumption level. Other embodiments are described and claimed. | 07-10-2014 |
20140359328 | METHOD AND SYSTEM FOR RUN-TIME REALLOCATION OF LEAKAGE CURRENT AND DYNAMIC POWER SUPPLY CURRENT - A method and system for dynamic or run-time reallocation of leakage current and dynamic power supply current of a processor. In one embodiment of the invention, the processor uses the variation in the leakage current of the processor to reduce the maximum current dissipation or power supply current of the processor (ICC | 12-04-2014 |
20150089254 | Controlling Power Consumption in Processor-Based Systems and Components Thereof - Since the maximum power consumption is largely a concern at the power supply domain, a limited number of nodes may be allowed to consume their maximum power consumption by preventing other nodes from consuming their maximum power consumption. This approach may be used either instead of or in cooperation with existing maximum power consumption regulators. | 03-26-2015 |
