Abstract :
The authors propose an encoding scheme suitable for a digital optical modified signed-digit arithmetic processor that is based on symbolic substitution. The processor performs binary addition and subtraction in an extremely parallel manner; i.e. the desired result is obtained in three steps, independent of word and array size of the input operands. The encoding scheme is designed to prevent the crosstalk problem
