Abstract :
The design and VLSI implementation of an ASIC chip, which performs real time conversion, the Red, Green, and Blue (RGB) color coordinates to CIE (Commission Internationale de l´Eclairage) standard L* (luminance), a* (redness-greenness), and b* (yellowness-blueness) color coordinates, is presented. High-speed operation of this ASIC is achieved by pipelining the input data, and performing parallel operations. The ASIC is implemented using CMOS, 2.0 μm, n-well process. It occupies an area of 1.55×1.45 mm2. The chip is intended to be used in colorimetry manufacturing inspection and robotics precision. Inputs are 3 bits each. a* and b* are 7 bits each, L* is 6 bits
