Abstract :
In this paper, a simple recoded trinary signed-digit (TSD) number representation for parallel optical computing is proposed. This technique performs multi-digit carry-free addition and borrow-free subtraction in constant time using only 50% of the minterms required in the most recently reported TSD arithmetic technique
