A graphics subsystem including a RAMDAC for connection to a graphics bus implemented on an integrated circuit chip separate from a graphics processor. In one embodiment, the graphics processor is configured to render digital image information in response to graphics commands and to store the digital image information in a memory. The RAMDAC IC includes a conversion unit, which includes a color mapping unit and a digital-to-analog converter and is configured to convert a representation of the digital image information into one or more analog signals for driving a video display. The graphics subsystem further includes a Direct Memory Access (DMA) controller implemented on the second integrated circuit chip. The DMA controller is configured to generate read requests to retrieve the digital image information stored in the memory to thereby cause the digital image information to be provided to the conversion unit. The DMA controller is further configured to generate write cycles to cause digital RGB display data received from the color mapping unit, in the conversion unit, to be provided for storage in a specified region of memory.
Method And System For Data Communications In Cloud Computing Architecture
Example embodiments of the present disclosure concern a system and method for selectively intercepting communications in a cloud computing environment by receiving communications from one or more thin-client terminal systems connected via a local area network, determining one or more recipients of each received communication, and based on a determination that the one or more recipients of a communication include only thin-client terminal systems connected via the local area network, intercepting the communication and preventing the communication from being transmitted to a central server connected to the local area network via a wide area network, storing the communication, and forwarding the communication to the one or more recipients connected to the local area network.
Memory Storage Via An Internal Compression Algorithm

SPANSION LLC - Sunnyvale CA
The subject specification discloses flash memory device with the capability of performing both internal compression as well as internal de-compression. Each of these actions takes place through appropriate algorithms. In normal operation, the compression occurs prior to a writing of data in a flash memory device. The compressed data travels to a storage location. The de-compression occurs after the reading of stored data and de-compressed data travels to an external system.

Techniques for use within computer systems that communicate with multiple different terminal systems using multiple different terminal protocols are disclosed. In one embodiment, a partial protocol converter module is installed in a computer server system to enable the computer server system to communicate with terminal systems that use terminal protocol other than the terminal protocol used natively by the computer server system. The partial protocol converter module directly accesses a screen buffer in the computer server system that is associated with the terminal systems that use terminal protocol other than the terminal protocol used natively by the computer server system. The partial protocol converter module detects updates to the screen buffer and encodes these display screen updates into a message using the native protocol used by the terminal system and then transmits that encoded message to the terminal system.
System And Method For Low Bandwidth Display Information Transport
Subir Ghosh - San Jose CA, US Gabriele Sartori - Fremont CA, US
A digital video transmission system that operates with three different video rendering paths. A first rendering path operates by receiving display requests and rendering bit-mapped graphics in a local screen buffer. The display information in that local screen buffer is then encoded and transmitted to a remote display system that recreates the content of that local screen buffer in a video buffer of remote display system. A second rendering path operates by receiving encoded video stream requests that can be decoded by the remote display system. Such encoded video streams are sent to the remote display system with minimal addition transport encoding. The third rendering path handles encoded video streams that cannot be handled natively by the remote display system. Such video streams may be either transcoded before transmission or decoded and stored within the local screen buffer.
System And Method For Virtual 3D Graphics Acceleration And Streaming Multiple Different Video Streams
A digital video transmission system that improves performance using 3D graphics acceleration hardware. A first system creates a virtual 3D graphics card for each terminal session executing on a server system that supports multiple users. The virtual 3D graphics card is assigned a share of processing ability on a physical 3D graphics accelerator. The virtual 3D graphics card uses the share of processing ability on the physical 3D graphics accelerator to render 3D graphics in a local screen buffer associated with the terminal session. The local screen buffer is encoded and transmitted to a remote display that recreates the screen display in a video buffer of remote display. A second system operates by using a physical 3D graphics accelerator in a server system to perform transcoding for multiple video streams. To best perform task switching, the task switching is performed on I-frame borders.
3D Graphics Acceleration In Remote Multi-User Environment
Systems and methods for providing graphics acceleration to one or more terminal systems are disclosed. In one embodiment, a virtual machine session is created and one or more cores of a graphics accelerator with a plurality of cores is assigned to a virtual machine session in order to render a virtual desktop for display at a terminal system.

nComputing Inc. - Redwood City CA
A device and a method of authenticating an electronic device are described. The method may comprise transmitting a token value and a parameter value to the electronic device and selecting a private key within the electronic device using the parameter value. The token value may be processed with a method selected by the parameter value to generate a processed token. The processed token may be compared with an expected processed token and the electronic device may be authenticated if the processed token compares favorably with said expected processed token.
