摘要:
Described is a technology by which a memory controller is a component of a hybrid memory device having different types of memory therein (e.g., SDRAM and flash memory), in which the controller operates such that the memory device has only a single memory interface with respect to voltage and access protocols defined for one type of memory. For example, the controller allows a memory device with a standard SDRAM interface to provide access to both SDRAM and non-volatile memory with the non-volatile memory overlaid in one or more designated blocks of the volatile memory address space (or vice-versa). A command protocol maps memory pages to the volatile memory interface address space, for example, permitting a single pin compatible multi-chip package to replace an existing volatile memory device in any computing device that wants to provide non-volatile storage, while only requiring software changes to the device to access the flash.

Described is a technology by which a computer display may quickly resume outputting video data following its awakening from a deep sleep state. Displayed settings are maintained in a memory, such as a memory of the display, while the display is in a sleep state. The settings are associated with a token maintained by a host computer system and display. Upon a need to awaken the display to output video data, the host computer system and the display communicate the token, whereby the display may confirm whether maintained settings are still valid for actual use with the host's video signals. If still valid, the display restores the maintained display settings as actual display settings. The restoring of previously maintained display settings is ordinarily significantly faster than conventional mechanisms that are presently used to configure a display upon wakeup, resulting in the user perceiving a near-instantaneous wakeup of a display.

摘要:
A display manager is configured to handle the drawing of windows on one or more displays for an application differently based on detected motion information that is associated with a device. The display manager may not display windows for some applications while motion is detected, while the display manager may display windows for other applications even when motion is detected. Motion enabled applications may interact with the display manager and motion information to determine how to display windows while motion is detected.

Various devices may include a short-range wireless transmitter and/or one or more short-range wireless readers. When a first device including the transmitter is placed near a second device including the one or more readers, a relative location of the first device may be determined. Information regarding the relative location of the first device, may be used to facilitate use of the first device with a processing device. In one embodiment, the processing device may automatically configure itself, such that the first device may be used with the processing device. In another embodiment, the processing device may provide feedback, such as, for example, step-by-step instructions to facilitate setup and use of the first device with the processing device. In some embodiments, an application program interface may provide information about the device to an application executing on the processing device.

As a pedestrian travels, various difficulties can be encountered, such as traveling through an unsafe neighborhood or being in an open area that is subject to harsh temperatures. A route can be developed for a person taking into account factors that specifically affect a pedestrian. Moreover, the route can alter as a situation of a user changes; for instance, if a user wants to add a stop along a route.

Described is a high speed nonvolatile memory device and technology that includes a controller coupled via interfaces to sets of nonvolatile storage, such as separate flash memory chips or separate regions of a single chip. The controller includes logic that processes write requests of arbitrary size, by interleaving writes among the interfaces, including by parallel writing among the interfaces. For example, the data may be received via direct memory access (DMA) transfers. The controller maintains information to allow the interleaved data to be reassembled into its correct relative locations when read back, such as by DMA. The high speed nonvolatile memory device thus provides a hardware device and software solution that allows a personal computer to rapidly boot or resume from a reduced power state such as hibernation. The high speed nonvolatile memory device also may be used for other data storage purposes, such as caching and file storage.
