In this paper, we propose the design of cubic root system. The proposed cubic root system is compared with the existing methods that use the piecewise linear method and Newton-Raphson algorithm. The existing methods have problems with error and gate count. However, the proposed algorithm has merits; hardware complexity and no error rate compared with the existing algorithm. This system is designed with VHDL and synthesized by using Samsung 0.35㎛ std90 library and Synopsys Design Analyzer.

In this paper, we propose the color emphasis algorithm by using the movement of chromaticity coordinates along the adaptive conversion line on CIE1931 Diagram, and this algorithm is designed to apply video system like TV. We have been already say that this algorithm emphasis the colors by moving the chromaticity coordinates on the CIE1931 diagram. And it can not convert the colors which are dissatisfied to viewers. To get this result, proposed algorithm is dividing into movable and non-movable area, using the two kinds of conversion curve to forbid rapid color conversion.
