摘要： 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.

摘要： A processor includes multiple physical cores that support multiple logical cores of different core types, where the core types include a big core type and a small core type. A multi-threaded application includes multiple software threads are concurrently executed by a first subset of logical cores in a first time slot. Based on data gathered from monitoring the execution in the first time slot, the processor selects a second subset of logical cores for concurrent execution of the software threads in a second time slot. Each logical core in the second subset has one of the core types that matches the characteristics of one of the software threads.

摘要： A heterogeneous processor architecture is described. For example, a processor according to one embodiment of the invention 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; virtual-to-physical (V-P) mapping logic to expose the set of large physical processor cores to software through a corresponding set of virtual cores and to hide the set of small physical processor core from the software.

摘要： A processor is operable to process conditional branches. The processor includes instruction fetch logic to fetch a conditional short forward branch. The conditional short forward branch is to include a conditional branch instruction and a set of one or more instructions that are to sequentially follow the conditional branch instruction in program order. The set of the one or more instructions are between the conditional branch instruction and a forward branch target instruction that is to be indicated by the conditional branch instruction. The processor also includes instruction conversion logic coupled with the instruction fetch logic. The instruction conversion logic is to convert the conditional short forward branch to a computationally equivalent set of one or more predicated instructions. Other processors are also disclosed, as are various methods and systems.

摘要： A processor of an aspect includes a set of registers capable of storing packed data. An execution unit is coupled with the set of registers. The execution unit is to access the set of registers in at least two different ways in response to instructions. The at least two different ways include a first way in which the set of registers are to represent a plurality of N-bit registers. The at least two different ways also include a second way in which the set of registers are to represent a single register of at least 2N-bits. In one aspect, the at least 2N-bits is to be at least 256-bits.
