Abstract:

A packet mapper prioritizes streams of data packets in a computer network, each data packet having a packet header containing feature values descriptive of the data packet. The packet mapper includes a mapping table that associates application-related features with network-reserved feature values from a range of feature values reserved for use by selected network data packet streams, and a feature value mapper that performs at least one of (i) in each packet header having an application-related feature value associated with a network-reserved feature value, substituting the associated network-reserved feature value for the application-related feature value, and (ii) in each packet header having a network-reserved feature value associated with an application-related feature value, substituting the associated application-related feature value for the network-reserved feature value.

Inventors:

Michael Kerby Chen - Palo Alto CA, US

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

G06F 12/00

US Classification:

711118, 711144, 711156

Abstract:

In some embodiments, the invention involves a system and method relating to software caching with bounded-error delayed updates. Embodiments of the present invention describe a delayed-update software-controlled cache, which may be used to reduce memory access latencies and improve throughput for domain specific applications that are tolerant of errors caused by delayed updates of cached values. In at least one embodiment of the present invention, software caching may be implemented by using a compiler to automatically generate caching code in application programs that must access and/or update memory. Cache is accessed for a period of time, even if global data has been updated, to delay costly memory accesses. Other embodiments are described and claimed.

International Classification:

H04N 5/222

US Classification:

34833301, 34833302, 34833312

Abstract:

Systems and methods of providing spatially dependent image exposure information to a user of a digital camera. The described approach is applicable to determination of image exposure quality in a digital camera system. In these applications an image is displayed in a first display mode wherein the exposure information is overlaid on the image or in a second display mode wherein the exposure information is eliminated or reduced and thus is less obstructive of the image. In the second display mode, a separate exposure warning optionally conveys a subset of the information displayed in the first display mode. The invention includes a user input operable to temporarily specify a change in the display of the image between the first mode and the second mode while an image is displayed, thus providing the user with direct control of the presence and duration of spatially dependent image exposure information.

International Classification:

G06F 9/45

US Classification:

717151, 717154, 718102, 718105

Abstract:

A method and system to optimize throughput of executable program code are provided. The system comprises a profiler to receive a representation of a plurality of functions, an aggregator, and a mapper to map the plurality of aggregates to a plurality of processors. The aggregator may be configured to create an aggregate for each function from the plurality of functions thereby creating a plurality of aggregates, choose an optimization action between grouping and duplication based on the number of aggregates in the plurality of aggregates, the number of available processing elements (PEs), and execution time of each aggregate, and perform the chosen optimization action.

US Classification:

455436, 455448

Abstract:

A method for providing a handoff in a network environment is provided that includes a mobile station operable to conduct a call. The mobile station is further operable to initiate a call leg autonomously such that a generic transfer function is invoked. The mobile station leverages the generic transfer function in order to execute a handoff for the mobile station.

Abstract:

Methods, systems, and apparatus, including computer program apparatus, implementing techniques for publishing, subscribing to, or playing live appliances. A live appliance includes a current virtual machine image. In publishing, a proxy file of a live appliance file type is provided to the publisher. The type is mapped to a live appliance player; so that when a proxy file is opened, the current virtual machine image is run. The player automatically binds a writeable file system external to the virtual machine image to the image to provide file storage that is accessible from within the virtual machine image and from a host operating system. The player also creates a subscription to the live appliance on the host computer if one does not exist when the proxy file is run. With the subscription, the player runs the then-current virtual machine image whenever the live appliance is run.

Abstract:

Systems and methods for detecting, installing and uninstalling a virtual machine monitor on a host device is provided. In general, in one aspect, a computer implemented method is provided. The computer implemented method includes initiating a user session on a host device, where the user session is initiated upon the insertion of a peripheral device into the host device. Additionally, a virtual machine monitor and a virtual machine are stored on the peripheral device and the virtual machine monitor is automatically installed on the host device. In some implementations, the virtual machine monitor is automatically uninstalled when the user session is terminated.
