Abstract: Power consumption and dissipation during sleep states of processors is reduced using a novel connected standby sleep state. In the connected standby sleep state a dedicated power plane is used to maintain processor context. To conserve power, unnecessary components on the processor are powered down, including all of the clock components, and wakeup sources previously directed to the processor are directed to a platform control hub. The platform control hub sustains certain architectural functions for the processor during connected standby sleep state, and manages the wakeup logic for returning the processor to the preceding sleep state.
Abstract: Using die side capacitors and embedded resistors, an advantageous power delivery network may be achieved. In some embodiments, the embedded resistors may be more precisely controllable. The number of die side capacitors may be reduced by combining embedded resistors with these capacitors to reduce costs. The embedded resistors may be provided within the metallization layers either at an upper layer or a lower layer, as two examples.

Abstract: In accordance with some embodiments of the present invention, de-interlacing may be accomplished by using an edge gradient to select a best interpolation direction for several adjacent pixels between two lines of interlaced video. The interpolation of the intermediate line is performed using the best direction. Then the pixels in the line above and below are analyzed to determine whether the interpolated pixel value should actually be used in view of the possible presence of artifacts.

Other embodiments are described and claimed.
Abstract: Interacting with a television program includes beginning playback of the program for perception by a user, analyzing the program to detect a cue within the program, automatically pausing playback of the program when the cue is detected, accepting user input data in response to the cue, resuming playback of the program when the user input data is received, and comparing the user input data to a non-user response. Interactivity provided by the program analysis, pausing playback, accepting user input data, resuming playback, and comparing operations supports execution of at least one of an entertainment application and an educational application at a user's site without requiring modification of the television program by a program provider.
Abstract: The leakage current and power consumption of phase change memories may be reduced using adaptive word line biasing. Depending on the particular voltage applied to the bitline of a programmed cell, the word lines of unselected cells may vary correspondingly. In some embodiments, the word line voltage may be caused to match the bitline voltage of the programmed cell.

Abstract: A pre-boot environment is disclosed that manages power of a computing device prior to an operating system runtime phase. The pre-boot environment may be implemented in a computing device having a storage device to store an operating system, a firmware device to store firmware having a boot loader to load and initiate execution of the operating system, and a processor to execute the firmware and the operating system. The firmware in response to being executed by the processor may result in the computing device monitoring operating conditions of the computing device, and initiating a power management response based upon the operating conditions of the computing device and a power management policy.
Abstract: Embodiments of apparatuses, methods, and systems detecting spin loops in a virtual machine environment are disclosed. In one embodiment, an apparatus includes detection logic and virtualization logic. The detection logic is to detect whether a guest is executing a spin loop. The virtualization logic is to transfer control of the apparatus from the guest to a host in response to the detection logic detecting that the guest is executing the spin loop.

Abstract: A method may include distributing ranges of addresses in a memory among a first set of functions in a first pipeline. The first set of the functions in the first pipeline may operate on data using the ranges of addresses. Different ranges of addresses in the memory may be redistributed among a second set of functions in a second pipeline without waiting for the first set of functions to be flushed of data.
Abstract: In accordance with some embodiments, a phase change memory may be formed in which the thermal conductivity in the region outside the programmed volume of phase change material is reduced. This may reduce the power consumption of the resulting phase change memory. The reduction in power consumption may be achieved by forming distinct layers of phase change material that have little or no mixing between them outside the programmed volume. For example, in one embodiment, a diffusion barrier layer may be maintained between the two distinct phase change layers. In another embodiment, a face centered cubic chalcogenide structure may be utilized.

Abstract: A transformer module includes a main primary winding coupled to a first input power source to receive a medium voltage signal, multiple main secondary windings each to couple to a power cell of a drive system, and an auxiliary primary winding coupled to a second input power source to receive a low voltage signal. The auxiliary primary winding can be spatially separated from the main windings to increase leakage inductance. The auxiliary primary winding can be active during a pre-charge operation to pre-charge the power cells.

Abstract: A technique for receiving a data stream including a spreading sequence packet of information containing a data payload and, in addition to the data payload, packet overhead including at least periodic information and at least one unique section of known coded information that defines a unique position within the packet, includes performing a plurality of processing steps to detect the position of the unique section within the packet of information. The steps include detecting the periodicity of the periodic information in a first processing step; in a second processing step after periodicity in the received data stream has been determined, estimating the position of the unique section within the packet of information; and in a third processing step, correlating the information in the packet of information about the estimated position with the known coded information.
