摘要： A method for dynamic power and performance calibration of a data processing system is provided in the illustrative embodiments. A synthesized program loaded in the data processing system is executed responsive to detecting an event in the data processing system. The synthesized program is configured to generate a set of data that is indicative of the data processing system's power-performance characteristics under varying conditions of operation. Using the set of data, a determination is made of a performance limit on an operation of the data processing system under present operating conditions of the data processing system. A parameter of the data processing system is calibrated to operate the data processing system within the performance limit.

摘要： Disclosed is a computer implemented method, computer program product, and apparatus for determining a safe lower bound for a commonly powered data processing system. A power management module operates the data processing system using at least one nominal operating parameter during an exploration periodicity, with the at least one nominal operating parameter being clock speed. The power management module determines whether a calibration period is occurring. The power management module calibrates the data processing system up to a measurement interval duration expiration. The power management module may repeat operating the data processing system using the at least one nominal operating parameter.

摘要： One embodiment provides a method of managing power in a computer system. A device of the computer system is operated at a selected power-state. The power consumption of the computer system is monitored. If the power consumption of the computer system is approaching or has exceeded a power cap selected for the computer system, then a request to reduce the power-state for the device is generated in response. The operating system is used to service the request to reduce the power-state according to the priority of the request. The reduced power state is forced out-of-band following the request to reduce the power-state if the request is not immediately serviceable by the operating system. Different approaches can be taken to force the reduced power state, using, for example, system management mode or a platform environment control interface.

摘要： A method and apparatus are provided for implementing soft-input soft-output iterative detectors/decoders. Soft-input information is added directly to incoming channel samples. Input signals comprising the received incoming channel samples with the added soft-input information are detected using a detector trellis. Branch metric terms are transformed to shift all time varying terms with the added soft-input information and some constant terms after an add compare select (ACS) unit. The shifted time varying terms with the added soft-input information and the shifted constant terms are added directly to state metric terms. The soft-input information is added directly to incoming channel samples and the computation of branch metrics is not affected. This allows optimization of a dual-max detector and soft-input soft-output Viterbi detector architectures to minimize hardware complexity and power consumption.
