A new ASIC for the measurement of appearance

This paper presents the design and VLSI implementation of a new color space converter chip which performs the conversion, in real-time, of the X, Y and Z color coordinates to the CIE L*u*v* perceptually uniform color space. The high speed of operation is achieved by pipelining the data in a vector fashion. The module is implemented using a DLM, 0.7 /spl mu/m, N-well, CMOS technology process and it occupies a silicon area of 5.73 mm/spl times/5.59 mm 32.03 mm/sup 2/. Its maximum speed of operation is 20 MHz and its throughput rate of operation is 200 MIPS. Targeted applications include display device modelling (matching of computer image processing to human sensing), device independent color reproduction, colorimetry instrumentation, and color machine vision applications.
