A programmable systolic array used for real time video signal processing is introduced. The processor is more than twice as fast and requires less hardware than multiplier-based processors. This is achieved by processing video signals that are coded more efficiently using differential pulse code modulation (DPCM). Tests carried out on the implementation of quadrature mirror filters (QMFs) indicate that images obtained using DPCM processing will have the same visual quality as those obtained using conventional processing
