  • Publication number: 20190012265
    Abstract: Providing multi-socket memory coherency using cross-socket snoop filtering in processor-based systems is disclosed. In this regard, a processor-based system provides a plurality of processor sockets, each associated with a coherency directory including a plurality of coherency directory entries each storing status indicators corresponding to memory granules of a local memory hierarchy. A point of serialization (POS) circuit of the processor-based system receives a memory access request including a local memory address, and retrieves a coherency directory entry corresponding to the local memory address. If a status indicator of the coherency directory entry corresponding to a memory granule associated with the local memory address indicates that a remote snoop is required, the POS circuit performs the remote snoop of one or more remote processor sockets indicated by the status indicator. If not, the POS circuit returns data from the local memory hierarchy for the memory access request.

  • Patent number: 6732119
    Abstract: The invention provides a perceptually-based system for pattern retrieval and matching, suitable for use in a wide variety of information processing applications. An illustrative embodiment of the system uses a predetermined vocabulary comprising one or more dimensions to extract color and texture information from an information signal, e.g., an image, selected by a user. The system then generates a distance measure characterizing the relationship of the selected image to another image stored in a database, by applying a grammar, comprising a set of predetermined rules, to the color and texture information extracted from the selected image and corresponding color and texture information associated with the stored image. The vocabulary may include dimensions such as overall color, directionality and orientation, regularity and placement, color purity, and pattern complexity and heaviness.

  • Patent number: 6360017
    Abstract: A method of encoding a video sequence including a sequence of video images includes first comparing elements of a portion of a first video image (e.g., pixels of a macroblock of a current frame) with elements of a portion of a second video image (e.g., corresponding pixels of a macroblock of a previous frame) to generate respective intensity difference values for the element comparisons. Then, a first value (e.g., one) is assigned to the intensity difference values that are above a visually perceptible threshold value and a second value (e.g., zero) is assigned to the intensity difference values that are at or below the visually perceptible threshold value. Next, the method includes summing the first and second values to generate a sum. If the sum is greater than a predetermined decision value, the portion of the first video image is encoded (e.g., motion compensated). The method is fully compatible and, thus, may be implemented with video standards such as, for example, H.261, H.

  • Patent number: 5682442
    Abstract: An image-processing system for perceptual coding of an image is disclosed. Coding is accomplished through an analysis of human visual sensitivity to noise in halftone images and an analysis of one or more signals representing the image to be coded. These analyses determine levels of noise. A first image is encoded so as to produce encoded values without introducing noise which exceeds a determined level of noise. Analysis of human visual sensitivity is carried out under a set of user determined conditions comprising viewing distance and lighting. The encoded image is communicated and decoded to produce representation of the first image for display. As part of displaying the representation of the first image, a halftoning process is carried out. The halftoning process may comprise the interpolation of data values of the representation of the first image as well as the addition of micro-dither to the representation.

  • Patent number: 5661525
    Abstract: Method and apparatus are disclosed for deinterlacing of an interlaced video frame sequence using interpolation estimations, such as spatial and temporal interpolations. Interpolations requiring a less accurate estimation of missing pixel values in the frames being deinterlaced, such that an interpolation may be performed with a minimum of error, are performed before interpolations which require a more accurate estimation of missing pixel values for performing an interpolation, such that estimates of missing pixel values are obtained with a minimum of error. Interpolation estimations are weighted in combination for computing approximations of missing pixel values in accordance with the errors associated with the respective interpolations.
