  • Motion estimation coprocessor
    Patent number: 5510857
    Abstract: A motion estimation coprocessor for use in a video data system. The motion estimation coprocessor may be used with a video memory that subdivides a P row.times.Q column image of pixels into several pages. The page structure enables efficient loading of video data into the coprocessor. The motion estimation coprocessor may perform several block matches simultaneously. The motion estimation coprocessor may perform exhaustive block matching or use a hierarchical search.

  • Video interface unit for mapping physical image data to logical tiles
    Patent number: 5486876
    Abstract: A video interface unit for transferring image data between video memory and video processing components interfaces with a video bus. The video interface unit has a partionable data buffer. The partionable buffer enables data to be accessed without redundant fetches of image data and for associated processing of data to be interleaved.

  • Apparatus and method for flexible control of digital signal processing devices
    Patent number: 5029079
    Abstract: A control apparatus for use with a digital signal processing device and associated memory units is described. The control apparatus determines, along with the electrical configuration of the digital signal processing device and associated memory units, the application of members of a signal array to be processed and the removal of the members of a processed signal array from the digital signal processing device. The control apparatus controls the location of data exchanged between the digital signal processing device and the associated memory units.
