    摘要: A method and apparatus for per core performance states in a processor. Per Core Performance States (PCPS) refer to the parallel operating of individual cores at different voltage and/frequency points. In one embodiment of the invention, the processor has a plurality of processing cores and a power control module that is coupled with each of the plurality of processing cores. The power control module facilitates each processing core to operate at a different performance state from the other processing cores. By allowing its cores to have per core performance state configuration, the processor is able to reduce its power consumption and increase its performance.

    摘要: In one embodiment, a multicore processor includes cores that can independently execute instructions, each at an independent voltage and frequency. The processor may include a power controller having logic to prevent a first core from execution at a requested turbo mode frequency if the first core has a stall rate greater than a first stall threshold, and concurrently allow a second core to execute at a requested turbo mode frequency if the second core has a stall rate less than a second stall threshold. Other embodiments are described and claimed.

    摘要: In one embodiment, a multicore processor includes a controller to dynamically limit a maximum permitted turbo mode frequency of its cores based on a core activity pattern of the cores and power consumption information of a unit power table. In one embodiment, the core activity pattern can indicate, for each core, an activity level and a logic unit state of the corresponding core. Further, the unit power table can be dynamically computed based on a temperature of the processor. Other embodiments are described and claimed.
