    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 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: Systems and methods of managing power provide for issuing a first operating requirement from a first processor core and issuing a second operating requirement from a second processor core. In one embodiment, the operating requirements can reflect either a power policy or a performance policy, depending upon the factor that is currently most important to software. Hardware coordination logic is used to coordinate a shared resource setting with the operating requirements. The hardware coordination logic is also able to coordinate the shared resource setting with independent resource settings of the first and second processor cores based on the operating requirements.
