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.

Abstract: In one embodiment, the present invention includes a multicore processor having first and second cores to independently execute instructions, the first core visible to an operating system (OS) and the second core transparent to the OS and heterogeneous from the first core. A task controller, which may be included in or coupled to the multicore processor, can cause dynamic migration of a first process scheduled by the OS to the first core to the second core transparently to the OS. Other embodiments are described and claimed.

Abstract: 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.
