One embodiment includes a personal computer device comprising at least one machine to execute a primary user operating system, a first physical memory to be used by the primary user operating system, at least one appliance operating system that is independent from the primary user operating system, a second physical memory to be sequestered from the primary user operating system and an access violation monitor to restrict access from the at least one appliance operating system to the second physical memory, wherein the access violation monitor is to run only when the at least one appliance operating system is invoked and at least one appliance operating system is to be invoked only after the primary user operating system has been suspended to a standby state.

Method and apparatus for controlling a primary operating system and an appliance operating system on the same machine

A method which includes initializing a device following a power cycle. The initialization includes an agent for the device implementing one or more command sequences to configure the device for operation on a computing platform. The one or more implemented command sequences are recorded and a configuration flag is asserted to indicate the device has been configured for operation on the computing platform. The configuration flag is included in a command configuration register. At least a portion of the recorded one or more command sequences and the command configuration register are stored in a persistent memory that includes non-volatile memory resident on the device. Based on an other power cycle, the device is to access the command configuration register. Based on the command configuration register, the device is to determine whether it is to configure itself by implementing the one or more stored command sequences. The device then configures itself based on that determination. Other implementations and examples are described in this disclosure.

Configuring a device for operation on a computing platform

A device can provide a first function and a second function. The first function can have a higher priority for power than the second function. An input element can receive an indication of a remaining capacity of a power source for the device. A comparison element can compare the indication of the remaining capacity of the power source to a power threshold associated with the second function. A control element can initiate a power control action with respect to the second function if the indication of the remaining capacity of the power source is below the power threshold.

Power prioritization among functions of a multi-function device

The memory content may be cached in the non-volatile cache when a computing system is entering Sstate. The non-volatile cache may be coupled to a bus that connects the disk drive with the disk controller. When resuming from Sstate, the memory content may be read from the non-volatile cache rather than from the slow disk drive, which facilitates instant-on resuming for the system. The caching process may be performed in an OS-transparent manner. During the caching process, data with contiguous addresses may be merged into a block of data. A mapping table may be created and stored in the non-volatile cache which includes multiple entries, each for a block of data. The mapping table facilitates data reading from the non-volatile cache to provide instant-on resuming from Sstate.

Method and apparatus for caching memory content on a computing system to facilitate instant-on resuming from a hibernation state

According to some embodiments, context information associated with a processing system is determined. It is then automatically arranged for a power state associated with the processing system to transition from a first power state to a second power state based on the context information.

Context based power management

Method and apparatus to manage power for a communication device having multiple radios are described.

Method and apparatus to manage power in a communication system

An instant-on PC is described which can be revived from a sleep state in a matter of seconds. This is carried out by keeping certain power-managed devices in a quickly-revivable state, e.g., the memory and certain elements on the motherboard chipset. Certain PCI devices are also enabled in a quick wake-up state so that they can wake up on a specified stimulus. The power consumption of each of these devices is obtained and it is determined if that power consumption exceeds the power capability of the auxiliary power supply. If not, the more aggressive sleep state is enabled. If so, however, the system takes action to either enter a less aggressive sleep state or to selectively de-enable certain ones of the devices that are in the keep-awake state. Preferably the choice of which to do is made by the user.

A method, apparatus, and storage medium for management at least two audio, video, or data (AVD) streams, wherein each AVD stream may comprise a plurality of stream segments. According to a preferred embodiment, the at least two AVD streams are stored in a file. A stream segment directory (SSD) table is stored, having an SSD entry for each stream segment in the file, wherein the SSD entry corresponding to each corresponding stream segment comprises a plurality of fields for characterizing the corresponding stream segment.

A method, apparatus, and storage medium for event tagging of at least one audio, video, or data (AVD) stream, each AVD stream comprising a plurality of AVD stream chunks. According to a preferred embodiment, the at least one AVD stream is stored. An event tag is stored in response to a signal indicating the beginning of an event, the event tag having an event stream information data (ESID) structure comprising an ESID entry for each AVD stream of the at least one AVD stream, each ESID entry comprising an offset for locating a corresponding AVD stream chunk of each active AVD stream of the at least one AVD stream.

A method, apparatus, and storage medium for temporal indexing of at least two audio, video, and data (AVD) streams, each AVD stream comprising a plurality of AVD stream chunks. A stream information data stream (SIDS) having a plurality of SIDS chunks is stored, each SIDS chunk corresponding to a corresponding AVD stream chunk for each of the at least two AVD streams. A temporal index stream (TIS) having a plurality of TIS chunks is also stored, each TIS chunk corresponding to a corresponding SIDS chunk. Each TIS chunk comprises a time stamp for indicating the current time and an offset for locating the corresponding SIDS chunk. Each SIDS chunk comprises an SIDS chunk entry for each of the at least two AVD streams that is currently active, each SIDS chunk entry comprising an offset for locating the corresponding AVD stream chunk of each active AVD stream of the at least two AVD streams.
