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： 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： An apparatus and method is described herein for optimization to prefetch throttling, which potentially enhances performance, reduces power consumption, and maintains positive gain for workloads that benefit from prefetching. More specifically, the optimizations described herein allow for bandwidth congestion and prefetch accuracy to be taken into account as feedbacks for throttling at the source of prefetch generation. As a result, when there is low congestion, full prefetch generation is allowed, even if the prefetch is inaccurate, since there is available bandwidth. However, when congestion is high, the determination of throttling falls to prefetch accuracy. If accuracy is high—miss rate is low—then less throttling is needed, because the prefetches are being utilized—performance is being enhanced. Yet, if prefetch accuracy is low—miss rate is high—then more prefetch throttling is needed to save power, because the prefetch are not being utilized—performance is not being enhanced by the large number of prefetches.

摘要： Methods and apparatus to provide for power consumption reduction in memories (such as cache memories) are described. In one embodiment, a virtual tag is used to determine whether to access a cache way. The virtual tag access and comparison may be performed earlier in the read pipeline than the actual tag access or comparison. In another embodiment, a speculative way hit may be used based on pre-ECC partial tag match to wake up a subset of data arrays. Other embodiments are also described.
