Abstract: A processor includes a first mode where the processor is not to use packed data operation masking, and a second mode where the processor is to use packed data operation masking. A decode unit to decode an unmasked packed data instruction for a given packed data operation in the first mode, and to decode a masked packed data instruction for a masked version of the given packed data operation in the second mode. The instructions have a same instruction length. The masked instruction has bit(s) to specify a mask. Execution unit(s) are coupled with the decode unit. The execution unit(s), in response to the decode unit decoding the unmasked instruction in the first mode, to perform the given packed data operation. The execution unit(s), in response to the decode unit decoding the masked instruction in the second mode, to perform the masked version of the given packed data operation.

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 set of two or more small physical processor cores; at least one large physical processor core having relatively higher performance processing capabilities and relatively higher power usage relative to the small physical processor cores; virtual-to-physical (V-P) mapping logic to expose the set of two or more small physical processor cores to software through a corresponding set of virtual cores and to hide the at least one large physical processor core from the software.

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.
