Implementation of a bipolar real-time image signal processor-RISP-II

The high-speed digital image signal processor RISP-II, an improved version of the original real-time image signal processor (RISP) for gray-level image processing, is discussed. RISP-II has a microprogrammable architecture and a per-chip processing speed of 100 million instructions per second. Multichip processing has been realized by two added features: parallelism and pipelining. In the multichip mode its processing power can easily be increased. As a result, RISP-II is capable of real-time processing of the image data of a moving object. RISP-II, implemented in an advanced bipolar ECL technology, has integrated 20600 elements on a chip of 6/spl times/6 mm/SUP 2/. Its power dissipation is 1.6 W.
