摘要:
A technique includes amplifying data signals from a memory bus interface. The amplified data signals are sampled, and the amplifier is selectively disabled in response to the absence of a predetermined operation occurring over the memory bus. In some embodiments of the invention, the amplification may be selectively enabled in response to the beginning of the predetermined operation over the memory bus.

Technologies for one-level memory (1LM) and two-level memory (2LM) configurations in a common platform are described. A processor includes a first memory interface coupled to a first memory device that is located off-package of the processor and a second memory interface coupled to a second memory device that is located off-package of the processor. The processor also includes a multi-level memory controller (MLMC) coupled to the first memory interface and the second memory interface. The MLMC includes a first configuration and a second configuration. The first memory device is a random access memory (RAM) of a one-level memory (1LM) architecture in the first configuration. The first memory device is a first-level RAM of a two-level memory (2LM) architecture in the second configuration and the second memory device is a second-level non-volatile memory (NVM) of the 2LM architecture in the second configuration.

In an embodiment, a processor includes a plurality of cores and power management logic. The power management logic may be to, in response to a first break event during a reduced power state in the processor, set an exit timer based on a platform latency tolerance, block a first plurality of break events from interrupting the reduced power state, and in response to a expiration of the exit timer, terminate the reduced power state. Other embodiments are described and claimed.

Embodiments of the invention are generally directed to systems, methods, and apparatuses for using interface frequency modulation to allow non-terminated operation and power reduction. In some embodiments, an apparatus includes an interface having a termination mode and a power management controller coupled with the interface. The apparatus may also include a power management controller coupled with the interface. In some embodiments, the power management controller is capable of dynamically reducing the operating frequency of the interface and disabling the termination mode to reduce the power consumed by the interface. Other embodiments are described and claimed.
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 method is described that involves driving a first current through a line and a termination resistance so that a logical value on the line changes from a first logical value to a second logical value. The method also includes holding the second logical value on the line by driving a second current through the line and the termination resistance where the second current less than the first current. An apparatus is described that includes a driver that drives a first current through a line and a termination resistance so that a logical value on the line changes from a first logical value to a second logical value. The driver holds the second logical value on the line by driving a second current through the line and the termination resistance. The second current is less than said first current.
