Abstract: 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.

Abstract: A design structure for a pipeline electronic processor device may be embodied in a machine readable medium for designing, manufacturing or testing a processor integrated circuit. The design structure may embody a pipeline electronic circuit that 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 design structure to achieve power conservation by incorporating clock-gating circuitry among the stages of the pipeline at clock gating opportunity locations that the simulation identifies.

Abstract: 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.
