Logic/Arithmetic Operation Using Color Light Encoding and Pre-operation Post-carry Processing Methods

색광 부호화와 전연산 후캐리 처리를 이용한 논리 및 산술연산

A capability of performing the optical logic and arithmetic operations is followed by an effective encoding technique. In this paper, we proposed the color light encoding technique. By using this encoding technique, the space bandwidth product(SBP) is minimized in the output plane. In addition, we proposed the pre-operation pro-carry processing method that performs faster than the same time operation and carry processing method in optical computing. We proposed that the color liquid crystal device(CLCD) is used as the encoded color light input source.
