Abstract :
A programmable video signal processor (HD-Picot system) has been developed. It has 64 homogeneous processors and processes signals at video rate including conventional TV and high definition television (HDTV) signals by adopting a reconfigurable structure and sophisticated control. The performance is about 14.3 giga operations per second, which can be increased by adding processors. Various functions are carried out by program, including spatio-temporal filtering, edge detection, motion-vector detection, geometric transformation, color processing, pattern matching, texture mapping, and image synthesis. It can be applied to a wide range of fields such as broadcasting, communication, machine vision, etc
