Optical Parallel Negabinary Arithmetic Based on Logic Operation and Signed digit Representation
One kind of optical parallel negabinary arithmetic is investigated. Based on sign digit negabinary representation, the two step addition and one step subtraction of arbitrary length operands can be performed. The arithmetic is realized by logic operations and implemented by the spatial encoding technique, which offers an efficient design of optical arithmetic logic unit(ALU).
