Digital processing of video signals has become commonplace in television studios. The required electronic components that were state-of-the-art in 1973 are now commodity items. However, the demands placed on the hardware by the processing algorithms have not remained static; the special effects, comb filtering, and bandwidth reduction techniques employed today impose a tremendous computational burden. The real time video signal path needs dedicated, highly pipelined digital circuits. To that end, two integrated circuits have been developed that address the practical problems faced by the video system designer. One, a high speed parallel multiplier, is opitmized for televisions's speed, resolution, accuracy, power, and size constraints. The other, an FIR filter chip, offers an even more efficient solution to the majority of signal filtering applications.
