Joint Spatial Encoding 방법을 이용한 변형부호화자리수 가산기 구현
Implementation of the modified signed digit number (MSD) adder using joint spatial encoding method
초록
An optical adder for a modified signed-digit(MSD) number system using joint spatial encoding method is proposed. In order to minimize the numbers of symbolic substitution rules, nine input patterns were divided into five groups of the same addition results. For recognizing the input reference patterns, masks and reference patterns without any other spatial operations are used. This adder is implemented by smaller system in size than a conventional adder.
