A VIDEO SIGNAL PROCESSOR FOR MOTION-COMPENSATED FIELD-RATE UP-CONVERSION IN CONSUMER TELEVISION

An IC for 100-Hz television has been realized implementing motion esti mation and compensation algorithms for high-quality upconversion and a judder-free motion portrayal of movie material. The four embedded vid eo signal processors on this IC provide a processing power of 10 giga- operation per second (GOPS). Their architecture was generated from an algorithm description using behavioral synthesis, The required 25-Gb/s memory bandwidth was realized by embedding 24 single/dual port SRAM/D RAM instances, The test approach includes full scan, boundary scan, fu nctional testing, built-in-self-test, and IDDq-test. The so-called ''N atural Motion'' feature implemented by this IC was demonstrated at the IFA '95 and received the European Video Innovation Award 95-96.
