摘要： In an embodiment, a processor includes at least one core including a first core. The first core includes memory execution logic to execute one or more memory instructions, memory dispatch logic to output a plurality of memory instructions to the memory execution logic, and reactive memory instruction tracking logic. The reactive memory instruction tracking logic is to detect an onset of a memory instruction high power event associated with execution of at least one of the memory instructions, and to indicate to the memory dispatch logic to throttle output of the memory instructions to the memory execution logic responsive to detection of the onset of the memory instruction high power event. The processor also includes cache memory coupled to the at least one core. Other embodiments are described and claimed.

摘要： Some implementations provide techniques and arrangements for adjusting a rate at which operations are performed by a processor based on a comparison of a first indication of power consumed by the processor as a result of performing a first set of operations and a second indication of power consumed by the processor as a result of performing a second set of operations. The rate at which operations are performed by the processor may be adjusted when the comparison indicates that a difference between the first indication of power consumed by the processor and the second indication of power consumed by the processor is greater than a threshold value.

摘要： Novel instructions, logic, methods and apparatus are disclosed to test transactional execution status. Embodiments include decoding a first instruction to start a transactional region. Responsive to the first instruction, a checkpoint for a set of architecture state registers is generated and memory accesses from a processing element in the transactional region associated with the first instruction are tracked. A second instruction to detect transactional execution of the transactional region is then decoded. An operation is executed, responsive to decoding the second instruction, to determine if an execution context of the second instruction is within the transactional region. Then responsive to the second instruction, a first flag is updated. In some embodiments, a register may optionally be updated and/or a second flag may optionally be updated responsive to the second instruction.
