摘要： A method and apparatus for dynamic power management of memories. In one embodiment of the invention, the power consumption of the memories is reduced based on the operating state of the memories. For example, in one embodiment of the invention, the power supply to the memories is reduced when the memories are in an inactive state by reducing and/or turning off the input voltage(s) to the memories. In one embodiment of the invention, the processing unit dynamically changes the strength of the On-Die Termination pull-up/pull-down resistance based on the memory operating mode, memory voltage, and memory temperature.

摘要： A mechanism for P-state feedback to operating system (OS) with hardware coordination is described herein. In one embodiment, an example of a process includes, but is not limited to, receiving data from a processor representing an average performance over a previous period of time, and determining a performance state (P-state) for a next period of time based in part on the data representing the average performance over the previous period of time. Other methods and apparatuses are also described.

摘要： A system includes a memory unit and a processor where the processor has a load buffer to store a first instruction and a cache controller to block the first instruction from dispatch into the cache controller until load data for load operations prior to the first instruction fetched from the memory unit are globally observed. The processor further may include a control register having a first mode storage to store a mode control selection for pre-serialization and a second mode storage to store a mode control selection for post-serialization to enable control of pre-serialization and post-serialization of load operations with respect to the first instruction. Other embodiments are described and claimed.

摘要： In one embodiment, the present invention includes a system-on-a-chip (SoC) with first and second cores, interface logic coupled to the cores, chipset logic coupled to the interface logic, and a virtual firewall logic coupled between the chipset logic and the second core. The interface logic may include a firewall logic, a bus logic, and a test logic, and the chipset logic may include a memory controller to provide for communication with a memory coupled to the SoC. In some system implementations, both during test operations and functional operations, the second core can be disabled during normal operation to provide for a single core SoC, enabling greater flexibility of use of the SoC in many different implementations. Other embodiments are described and claimed.
