Processor system for realtime video signal processing

A 10 ns programmable signal processor system for realtime applications in video signal and image processing has been developed and realised. Up to six instructions can be processed in one operation cycle of 10 ns. The high data throughput is attained by pipeline-structure and parallel circuit design. Several program realisations using this processor system have demonstrated that realtime processing of broadband signals with such different algorithms as edge-extractions, two-dimensional DPCM and moving-pattern generation are possible in a programmable processor.
