摘要: In an embodiment, a processor includes a plurality of cores and a cache unit reserved for a first core of the plurality of cores. The cache unit may include a first cache slice, a second cache slice, and power logic to switch operation of the cache unit between a first operating mode and a second operating mode. The first operating mode may include use of both the first cache slice and the second cache slice. The second operating mode may include use of the first cache slice and disabling the second cache slice. Other embodiments are described and claimed.

摘要: In an embodiment, a processor includes multiple cores and a power controller. The power controller may include a hardware duty cycle (HDC) logic to cause at least one logical processor of one of the cores to enter into a forced idle state even though the logical processor has a workload to execute. In addition, the HDC logic may cause the logical processor to exit the forced idle state prior to an end of an idle period if at least one other logical processor is prevented from entry into the forced idle state. Other embodiments are described and claimed.

摘要: In an embodiment, a processor includes a core to execute instructions, where the core includes a clock generation logic to receive and distribute a first clock signal to a plurality of units of the core, a restriction logic to receive a restriction command and to reduce delivery of the first clock signal to at least one of the plurality of units. The restriction logic may cause the first clock signal to be distributed to the plurality of units at a lower frequency than a frequency of the first clock signal. Other embodiments are described and claimed.
