A simple parallel optical computing technique using recoded quaternary signed-digit arithmetic is presented in this paper. An efficient shared content-addressable memory-based optical implementation that employs a fixed number of minterms for any operand length is developed. This technique requires the minimum number of minterms compared with similar previously reported techniques.
