    摘要: An integrated circuit includes a plurality of resonant clock domains of a resonant clock network. Each resonant clock domain has at least one clock driver that supplies a portion of clock signal to an associated resonant clock domain. The resonant clock network operates in a resonant mode with inductors connected to pairs of resonant clock domains at boundaries between the resonant clock domains. Each inductor forms an LC circuit with clock load capacitance in the pair of resonant clock domains to which the inductor is connected.

    摘要: A system includes a plurality of processor cores and a power management unit. The power management unit may be configured to independently control the performance of the processor cores by selecting a respective thermal power limit for each of the plurality of processor cores dependent upon an operating state of each of the processor cores and a relative physical proximity of each processor core to each other processor core. In response to the power management unit detecting that a given processor core is operating above the respective thermal power limit, the power management unit may reduce the performance of the given processor core, and thereby reduce the power consumed by that core.

    摘要: A method for controlling power consumption while maximizing processor performance. The method includes, for a time interval of operation in a first operational state, determining an amount of power consumed during by one or more cores of a processor, calculating, a power error based on the amount of power consumed in the time interval, obtaining a power error term for the interval by adding the power error to a power error term from a previous time interval, and comparing the power error term to at least a first error threshold. If the power error term is outside a range defined at least in part by the first error threshold, the method exits the first operational state and enters a second operational state. If the power error term is within the range defined at least in part by the first error threshold, operation continues in the first operational state.

    摘要: A system and method for efficient reporting of power usage. A power reporting unit within a processor receives a power consumption number once every sample interval from a power monitor. The power monitor determines a power consumption number based on data corresponding to activity levels of one or more functional blocks within the processor. This data corresponds to each of a number of sampled signals within the one or more functional blocks rather than temperature. Thus, the data is independent of environment temperature variations. An average power consumption number is computed based on received power consumption numbers for a running time interval, wherein the running time interval is larger than the sample interval. This value is conveyed to an external agent, such as a controller for a data center rack system. Responsive to receiving and processing the average power consumption number, the external agent may perform one or more actions. For example, the external agent may cause changes in a cooling system.
