IN RECENT YEARS, a new class of applications, requiring the transfer of digital video data, has emerged. Among the most technologically challenging are satellite-based geographical information systems that transmit high-resolution image sequences from various types of image sensors. To meet the available channel rate, these systems use video compression formats similar to those recommended by the ITU-T H.263 and ISO MPEG-2 standards. 1,2 The systems require arithmetic performance ranging from 1

Today, only video-processing systems that use multiple commercially available digital signal processors in parallel can meet these computation requirements. In addition, such systems need dynamic RAM (DRAM) for image frame storage, a memory controller, and video interfaces adapted to the image sensors. Consequently, the systems consist of a signifi-6 This 16.89-cm 2 multiprocessor system performs coding of high-resolution video streams in real time. Redundancy and self-reconfiguration techniques ensure high reliability with a suitable yield.
