Nominal decomposition of colour space transformation for the computer system for the reconfigurable computing and SA-C programming

摘要

A nominal decomposition is proposed to compute the colour space transformation in single assignment C (AS-C) language to shorten the execution time. The chromaticity coordinate transformation will be used by using fixed-point nominal decomposition. The look-up table for the gamma curve function mapping is also developed by illustrating two Taylor expansion types. The variables are decomposed into two corresponding values: nominal value and base value. The numerical results will verify that the developed algorithm can save the execution time. The developed algorithm can be very useful to implement the computer display and printer system in the firmware interface aspects.
