摘要: A processor saves micro-architectural contexts to increase the efficiency of code execution and power management. Power management hardware during runtime monitors execution of a code block. The code block has been compiled to have a reserved space appended to one end of the code block. The reserved space includes a metadata block associated with the code block or an identifier of the metadata block. The hardware stores a micro-architectural context of the processor in the metadata block. The micro-architectural context includes performance data resulting from a first execution of the code block. The hardware reads the metadata block upon a second execution of the code block and tunes the second execution based on the performance data.

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.

摘要: A system for measuring and managing thermal operations of a processor core on a semiconductor die using a sensor positioned in a hotspot of the processor core. A measured temperature reading is determined based upon a temperature sensed by the sensor. Interrupt signals and a software readable register indicating temperature information provide feedback about the thermal environment to the processor. Based upon the measured temperature reading, the interrupt signals direct the processor to modify operation.
