Real-time vector pipeline colour space transformer

Abstract

The design and implementation, using custom ICs, of a new real-time vector pipeline colour space transformer, which performs the transformation of the RGB colour coordinates to chromaticity coordinates is presented. Its minimum rate of operation is 66-5 MIPS and it can handle high resolution colour images of up to 682pizels per horizontal line. The high speed of operation was achieved by pipelining the data in a vector fashion. The device is intended to be used as the front end of colour machine vision systems in industrial pattern recognition, where the need for short processing times is crucial.
