Abstract: A processor of an aspect includes at least one lower processing capability and lower power consumption physical compute element and at least one higher processing capability and higher power consumption physical compute element. Migration performance benefit evaluation logic is to evaluate a performance benefit of a migration of a workload from the at least one lower processing capability compute element to the at least one higher processing capability compute element, and to determine whether or not to allow the migration based on the evaluated performance benefit. Available energy and thermal budget evaluation logic is to evaluate available energy and thermal budgets and to determine to allow the migration if the migration fits within the available energy and thermal budgets. Workload migration logic is to perform the migration when allowed by both the migration performance benefit evaluation logic and the available energy and thermal budget evaluation logic.

Abstract: A heterogeneous processor architecture and a method of booting a heterogeneous processor is described. A processor according to one embodiment comprises: a set of large physical processor cores; a set of small physical processor cores having relatively lower performance processing capabilities and relatively lower power usage relative to the large physical processor cores; and a package unit, to enable a bootstrap processor. The bootstrap processor initializes the homogeneous physical processor cores, while the heterogeneous processor presents the appearance of a homogeneous processor to a system firmware interface.

Abstract: A heterogeneous processor architecture is described. For example, a processor according to one embodiment of the invention comprises: a first set of one or more physical processor cores having first processing characteristics; a second set of one or more physical processor cores having second processing characteristics different from the first processing characteristics; virtual-to-physical (V-P) mapping logic to expose a plurality of virtual processors to software, the plurality of virtual processors to appear to the software as a plurality of homogeneous processor cores, the software to allocate threads to the virtual processors as if the virtual processors were homogeneous processor cores; wherein the V-P mapping logic is to map each virtual processor to a physical processor within the first set of physical processor cores or the second set of physical processor cores such that a thread allocated to a first virtual processor by software is executed by a physical processor mapped to the first virtual processor from the first set or the second set of physical processors.
