<p>The present invention pertains to integrated circuit system based on novel architecture of Video-Instruction-Set-Computing (VISC). The integrated circuit comprises a plurality of functional units to independently execute the tasks of remote communication, bandwidth adaptation, application control, multimedia management, and universal video encoding. The integrated circuit is also comprised of scalable formatter element connecting to the functional units which can inter-operate arbitrary external video formats and intelligently adapt to selective internal format depending upon the system throughput and configuration. Additionally, there is a smart memory element connecting to the functional units and scalable formatter, which can access, store, and transfer blocks of video data based on selective internal format. In the preferred embodiment, the integrated circuit is also comprised of an embedded RISC or CISC co-processor element in order to execute DOS, Windows, NT, Macintosh, OS2, or UNIX applications. In a more preferred embodiment, the integrated circuit includes a real time object oriented operation system element wherein concurrent execution of the application program and real time VISC based video instruction sets can be performed. The present invention is designed to sustain the evolution of a plurality of generations of the VISC microprocessors. These novel VISC microprocessors can be efficiently used to perform wide range of real time distributed video signal processing functions for applications such as interactive video, HDTV, and multimedia communications.</p> |
