SELECTIVE LIMITS ON PROCESSOR TURBO MODES

摘要

A method, computer program product and system for controlling the maximum turbo mode of a processor in a turbo boost state. The method comprises limiting a maximum turbo mode available to the processor by over-reporting the amount of current drawn by the processor to the current monitoring feedback line to the processor, wherein the processor uses the over-reported current to maintain operation of the processor within performance specifications of the processor. An automatic calibration routine may be used to determine nominal amounts of current over-reporting that may be used to prevent the processor performance from exceeding the maximum turbo mode. In one embodiment, a digital potentiometer is included in the voltage regulator circuit to over-report the current as instructed.
