Abstract: In one embodiment, the present invention includes a processor having multiple domains including at least a core domain and a non-core domain that is transparent to an operating system (OS). The non-core domain can be controlled by a driver. In turn, the processor further includes a memory interconnect to interconnect the core domain and the non-core domain to a memory coupled to the processor. Still further, a power controller, which may be within the processor, can control a frequency of the memory interconnect based on memory boundedness of a workload being executed on the non-core domain. Other embodiments are described and claimed.

Abstract: Embodiments of processors, methods, and systems for dynamic offlining and onlining of processor cores are described. In an embodiment, a processor includes a plurality of cores, a core status storage location, and a core tracker. Core status information for at least one of the plurality of cores is the be stored in the core status storage location. The core status information is to include a core state to be used by a software scheduler. The core state is to be one of a plurality of core state values including an online value, a requesting-to-go-offline value, and an offline value. The core tracker is to track usage of the at least one core and to change the core state from the online value to the requesting-to-go-offline value in response to determining that usage has reached a predetermined threshold.

Abstract: Methods and apparatus relating to autonomous C state mechanism and computational engine alignment for improved processor power efficiency. are described. An embodiment determines whether a semiconductor package should enter a package C state based on energy consumption values for entry into and exit from the package C state, an amount of time the semiconductor package stayed in the package C state previously, and one or more breakeven time points between the various package C states. Another embodiment detects a delay by an imaging computational unit of a processor to enter a low power consumption state relative to one or more other computational units of the processor. The logic causes the imaging computational unit to enter the low power consumption state in response to detection of the delay. Other embodiments are also disclosed and claimed.

Abstract: An apparatus and method are described for coupling a front end core to an accelerator component (e.g., such as a graphics accelerator). For example, an apparatus is described comprising: an accelerator comprising one or more execution units (EUs) to execute a specified set of instructions; and a front end core comprising a translation lookaside buffer (TLB) communicatively coupled to the accelerator and providing memory access services to the accelerator, the memory access services including performing TLB lookup operations to map virtual to physical addresses on behalf of the accelerator and in response to the accelerator requiring access to a system memory.
