  • Patent number: 8386687
    Abstract: A method and apparatus for data transfer includes receiving a first data packet across a first bi-directional bus and receiving a second data packet across a second bi-directional bus. Next, the first data packet is written to a first register operably coupled to the first bi-directional bus and the second bi-directional bus. The second data packet is written to a second register operably coupled to the first bi-directional bus and the second bi-directional bus. The second data packet is then transferred across the first bi-directional bus and the first data packet is transferred across the second bi-directional bus, thereby providing data transfer across a plurality of bi-directional buses and providing for data to be transferred across those buses to be stored at an intermediate register so that the data may be transferred in the next clock cycle, overcoming any latency requirements.

  • Publication number: 20130010168
    Abstract: A graphics multi-media integrated circuit (GMIC) is connected to a host processor over two serial links: a half duplex bi-directional serial link which accords to a display serial interface protocol, and a uni-directional serial link which accords to a camera serial interface protocol. The GMIC receives packets from the host over the half duplex bi-directional serial link and processes these packets. The GMIC sends packets over the uni-directional serial link. A packet from the host can request a processing operation by the GMIC or can initiate a memory operation at the memory of the GMIC. The GMIC can also send packets to the host to initiate a host memory operation and may be connected to a display over a bi-directional serial link and to a camera over a uni-directional serial link and a bi-directional control link allowing the host to control the display and camera.

  • Patent number: 8350867
    Abstract: A method includes detecting one of an application access or a file type access, and configuring, in response to detecting the application or file type access, automatically without user interaction, a display system in an image quality configuration for the application or the file type where the image quality configuration is based on providing best image quality with respect to the application or the file type. Configuring the display system in an image quality configuration, may involve determining that a profile associated with the application or associated with the file type is stored in memory, and configuring the display system according to the profile. The method may adjust at least one anti-aliasing parameter or at least one anisotropic filter parameter. The method may monitor an operating system to obtain an indication that an application has been accessed or that a file type has been accessed.

  • Publication number: 20120314758
    Abstract: A method and apparatus are described for processing video data. In one embodiment, a processor is provided with a video compression engine (VCE) that has a memory having a plurality of rows and a plurality of columns of addresses. Video data, (luma data or chroma data), is written in row (i.e., raster) order into the addresses of the memory, and then the data is read out of the addresses in column order. Data is written into the addresses of the columns of the memory as they are read out, which is subsequently read out in row order. This process of switching back and forth between reading and writing data in row and column order continues as the data is read and processed by an encoder to generate a compressed video stream.

  • Publication number: 20120314777
    Abstract: A method and apparatus are described for generating a display data stream for transmission to a remote display. A display control unit in a processor is configured to multiplex the outputs of a plurality of display controllers to generate a video data stream. A video compression engine (VCE) in the processor receives the video data stream directly from the display control unit without having to go through an external memory or an external display interface. The VCE compresses the video data stream, and optionally encrypts the video data stream. In one embodiment, audio and video data streams may be synchronized into a multiplexed, (and optionally encrypted), audio/video stream before being forwarded for transmission to a remote display. In another embodiment, separate audio and video streams (optionally encrypted) may be forwarded for transmission to the remote display.

  • Patent number: 8326053
    Abstract: A method and apparatus provides for block based image compression with multiple non-uniform block encodings. In one embodiment, an image is divided into blocks of pixels. In one embodiment the blocks are four pixels by four pixels, but other block sizes are used in other embodiments. In one embodiment, a block of pixels in the original image is compressed using two different methods to produce a first and second compressed block. Thus, each block in the original image is represented by two, typically different, compressed blocks. In one embodiment, color associated with a pixel is determined by combining the compressed information about the pixel in the first compressed block with information about the pixel in the second compressed block. In another embodiment, global information about the image is combined with the information in the first and second compressed blocks.
