    摘要: A processor saves micro-architectural contexts to increase the efficiency of code execution and power management. A save instruction is executed to store a micro-architectural state and an architectural state of a processor in a common buffer of a memory upon a context switch that suspends the execution of a process. The micro-architectural state contains performance data resulting from the execution of the process. A restore instruction is executed to retrieve the micro-architectural state and the architectural state from the common buffer upon a resumed execution of the process. Power management hardware then uses the micro-architectural state as an intermediate starting point for the resumed execution.

    摘要: In one embodiment, a processor includes a core with a front end unit, at least one execution unit, and a back end unit. Multiple voltage drop detectors can be located within the core each to output a voltage drop signal when a detected voltage falls below a threshold voltage. In turn, a current transient logic coupled to receive the voltage drop signals can control a micro-architectural parameter of at least one of the front end unit, execution unit and back end unit responsive to receipt of a voltage drop signal. Other embodiments are described and claimed.

    摘要: A processor may include a core and an uncore area. The power consumed by the core area may be controlled by controlling the Cdyn of the processor such that the Cdyn is within an allowable Cdyn value irrespective of the application being processed by the core area. The power management technique includes measuring digital activity factor (DAF), monitoring architectural and data activity levels, and controlling power consumption by throttling the instructions based on the activity levels. As a result of throttling the instructions, throttling may be implemented in 3rd droop and thermal design point (TDP). Also, the idle power consumed by the uncore area while the core area is in deep power saving states may be reduced by varying the reference voltage VR and the VP provided to the uncore area. As a result, the idle power consumed by the uncore area may be reduced.
