摘要:
A method of obtaining data, comprising at least one sector, for use by at least a first thread wherein each processor cycle is allocated to at least one thread, includes the steps of: requesting data for at least a first thread; upon receipt of at least a first sector of the data, determining whether the at least first sector is aligned with the at least first thread, wherein a given sector is aligned with a given thread when a processor cycle in which the given sector will be written is allocated to the given thread; responsive to a determination that the at least first sector is aligned with the at least first thread, bypassing the at least first sector, wherein bypassing a sector comprises reading the sector while it is being written; and responsive to a determination that the at least first sector is not aligned with the at least first thread, delaying the writing of the at least first sector until the occurrence of a processor cycle allocated to the at least first thread by retaining the at least first sector in at least one alignment register, thereby permitting the at least first sector to be bypassed.

摘要:
A pipeline electronic circuit and design methodology enables power conservation in the stages of the pipeline via a simulation that identifies clock-gating opportunities among the stages of the pipeline. In one embodiment, simulation results assist a designer in the design of the pipeline electronic circuit to achieve power conservation by incorporating clock-gating circuitry among the stages of the pipeline at clock gating opportunity locations that the simulation identifies.
摘要:
A mechanism for controlling instruction fetch and dispatch thread priority settings in a thread switch control register for reducing the occurrence of balance flushes and dispatch flushes for increased power performance of a simultaneous multi-threading data processing system. To achieve a target power efficiency mode of a processor, the illustrative embodiments receive an instruction or command from a higher-level system control to set a current power consumption of the processor. The illustrative embodiments determine a target power efficiency mode for the processor. Once the target power mode is determined, the illustrative embodiments update thread priority settings in a thread switch control register for an executing thread to control balance flush speculation and dispatch flush speculation to achieve the target power efficiency mode.

摘要:
A device for controlling power parameters in a microprocessor includes a resource activation control unit for controlling the maximum power of the microprocessor and two or more resources. The resource activation control unit controls the activation of the resources such that the consumed and dissipated power of the microprocessor does not exceed a power bound which is configurable to a predetermined value below the maximum power.
