A computer architecture includes a first operating system (COS), which may be a commodity operating system, and a kernel, which acts as a second operating system. The COS is used to boot the system as a whole. After booting, the kernel is loaded and displaces the COS from the system level, meaning that the kernel itself directly accesses predetermined physical resources of the computer. All requests for use of system resources then pass via the kernel. System resources are divided into those that, in order to maximize speed, are controlled exclusively by the kernel, those that the kernel allows the COS to handle exclusively, and those for which control is shared by the kernel and COS. In the preferred embodiment of the invention, at least one virtual machine (VM) runs via a virtual machine monitor, which is installed to run on the kernel. Each VM, the COS, and even each processor in a multiprocessor embodiment, are treated as separately schedulable entities that are scheduled by the kernel. Mechanisms for high-speed I/O between VM's and I/O devices are also included.

A camera solution includes an image sensor and an image processing and control system. At least two different operating modes are supported, with one of the modes having a higher dynamic range. Control of the dynamic range is provided at the system level. The system supports statically or dynamically selecting an operating mode that determines the dynamic range of a camera. In one implementation, the system supports the use of either a conventional image sensor that does not natively support a high dynamic range or a dual-mode image sensor.

A method for a client module to provide a channel selection request in a multimedia system begins by receiving an input signal from a client. The method continues by interpreting the input signal to determine type of signal. The method continues, when the type of signal is control information, by determining whether the control information relates to a local command or a system-level command. The method continues, when the control information relates to a system-level command, by processing the control information for conveyance to a multimedia server to produce a control message. The method continues by transmitting the control message to the multimedia server.

The system may provide suggestions to workers based on their schedules and activities that the workers have to perform. Users of the system may configure the criteria used in determining which suggestions to provide to workers. The system may refine the suggestions provided to workers based on feedback received regarding the suggestions previously provided.

A system-level text correction service (330) is provided. The service (330) includes monitoring (410) the input of text (340) on a computer system, identifying an incorrect input word in a first application. Correction proposal words are retrieved from a system-level dictionary (320), wherein the system-level dictionary (320) stores a reference word with an identifier of at least one application type in which the reference word is used. The correction proposal words are ranked according to the similarity of the proposal word to the input word and by comparing the first application to the application types of the reference word.

A system-level management unit generates a system processing and makes a processing request to a task allocation unit of a user-level management unit. The task allocation unit schedules the system processing according to a procedure of an introduced user-level scheduling. A processing unit assigned to execute the system processing sends a notification of acceptability of the system processing to a main processing unit, by halts an application task in appropriate timing or when the processing of the current task is completed. When the notification is received within the time limit for execution, the system-level management unit has the processing unit start the system processing.

In preferred embodiments, the device includes at least two subsystems and hardware mechanisms that automatically seek the lowest power state for the device that does not impact performance of the device or of a system that includes the device. Preferably, the device includes a control unit operable in any selected one of multiple power management modes, and system software can intervene to cause the control unit to operate in any of these modes.

A new system-level approach to managing the delivery of DC voltage and current. Several system level functions may be enabled without requiring separate ICs to perform those functions. Supervisory functions for a voltage converter may be performed by a central control module or chip that may be coupled to point-of-load voltage converters comprised in digital power management devices (DPMD) through a serial digital bus. The DPMDs may also use the high-speed serial digital bus to provide real-time feedback information to the central control module or chip. Single DPMDs may be combined together in a current sharing configuration in a “plug-and-play” fashion, where the control logic in each DPMD is capable of automatically establishing control loops required a multi-phase supply. Feedback necessary for establishing control may be transmitted across the digital bus coupling the devices. The supervisory functions may be included in each DPMD, which may communicate with each other over a serial digital bus, where the DPMDs singly or together may operate to perform control of their respective POLs, enabling configurations that do not require a central control module.

A system and method for mobile terminal users who play networked games to communicate with each other. Messages to be sent between players and methods of sending the messages are predefined either by a game player or at the system level. These messages can then be sent in an easy way by the game player from his mobile terminal to another player or potential player for any of various game-related purposes.

A virtual machine monitor (VMM) is included in a computer system that has a protected host operating system (HOS). A virtual machine running at least one application via a virtual operating system is connected to the VMM. Both the HOS and the VMM have separate operating contexts and disjoint address spaces, but are both co-resident at system level. A driver that is downloadable into the HOS at system level forms a total context switch between the VMM and HOS contexts. A user-level emulator accepts commands from the VMM via the system-level driver and processes these commands as remote procedure calls. The emulator is able to issue host operating system calls and thereby access the physical system devices via the host operating system. The host operating system itself thus handles execution of certain VMM instructions, such as accessing physical devices.

The invention relates to a system level virtualization technology and an energy-saving technology in the field of the structure of a computer system, and discloses an energy-saving method of a cloud data center based on virtual machine migration and load perception integration. The method comprises the steps: dynamically completing the migration and the reintegration of the load of a virtual machine in the cloud data center by monitoring the resource utilization rate of a physical machine and the virtual machine and the resource use condition of current each physical server under the uniform coordination and control of an optimized integration strategy management module of the load perception and an on-line migration control module of the virtual machine, and tuning off the physical servers which run without the load, so that the total use ratio of the server resource is improved, and the aim of energy saving is achieved. The energy-saving method of the cloud data center based on the virtual machine on-line migration and the load perception integration technology is effectively realized, the amount of the physical servers which are actually demanded by the cloud data center is reduced, and the green energy saving is realized.

A bidirectional radio frequency identification (RFID) network system and method are presented. The system allows users to configure, monitor, and manage different sensor devices by using a graphical user interface real-time. The reconfiguration is done through a network management computer at the top system level that receives user input, generates code images according to the user input, and appropriately routes the code images to sensor routers that directly control the sensors. If the system is multi-layered, some code images are also sent to the intermediate-level network management computers. The system allows users to not only monitor a business flow but react to problematic situations quickly by adjusting the workflow. The aspect-oriented nature of the system allows users to reconfigure the system based only the Functionality aspects without worrying about the Partitioning aspects (e.g., how the network and the sensors are physically connected).

A set of system-level high availability services for computer systems, including a service that functions in general terms like an extension of the operating system. By providing High Availability (HA) at the system-level, modifications to the applications or the operating system kernel are not required.

One aspect of the present invention includes enabling the efficient transfer of deduplicated data between storage pools in a storage management system without unnecessary reassembly and deduplication of data objects. In one embodiment, the storage management system tracks deduplication information for the data chunks of data objects within an index at the storage management system level, in addition to tracking storage information for each data object within another index at the storage management system level. The data chunk deduplication information is then accessible by any storage pool. Accordingly, transfers of the data objects and data chunks of the data object are easily facilitated, even between non-deduplicating and deduplicating storage pools.

An uninterruptible power supply (UPS) system and control method thereof is provided. The system contains a plurality of UPS modules connected in parallel, and each module is equipped with full uninterruptible power supply capabilities, and redundant control logic and functional capabilities for self-initiated role detection, master arbitration and parallel processing. The UPS system is self-initialized through a master arbitration process to elect a virtual master among the peers for maintaining inter-unit signaling between parallel UPS modules and controlling the parallel operation. If the virtual master is failed, other UPS modules will initiate the role detection and master arbitration to re-elect a new virtual master. Parallel operation is accomplished without any external controller; the system can be operated with only one UPS module; distribution of adequate resource to each module is properly arranged, thus the risks of system-level single-point failure are much reduced.

The present system and associated method resolve the problem of providing statistical performance guarantees for applications generating streams of read/write accesses (I/Os) on a shared, potentially distributed storage system of finite resources, by initiating throttling whenever an I/O stream is receiving insufficient resources. The severity of throttling is determined in a dynamic, adaptive way at the storage subsystem level. Global, real-time knowledge about I/O streams is used to apply controls to guarantee quality of service to all I/O streams, providing dynamic control rather than reservation of bandwidth or other resources when an I/O stream is created that will always be applied to that I/O stream. The present system throttles at control points to distribute resources that are not co-located with the control point. A competition model is used with service time estimators in addition to estimated workload characteristics to determine which I/O needs to be throttled and the level of throttling required. A decision point issues throttling commands to enforcement points and selects which streams, and to what extent, need to be throttled.
