Abstract
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.
