Paper Abstract

A new scheme for digital optical computing, utilizing a non-holographic opto-electronic addressable memory (CAM), is discussed. To illustrate the performance of this arithmetic processor, the design of an optical binary carry look-ahead adder (CLA), also, the design of a binary, a logarithmic number (LN) and a residue number (RN) multipliers are presented. Compared to existing opto-electronic approaches, this non-holographic CAM offers a number of practical advantages, such as fast processing speed, ease of optical implementation and alignment. Two spatial input data encoding techniques, an active low and high, are discussed. A multioperation multibit CAM processor is presented. Experimental results for a CLA adders; and a binary, residue and logarithmic number multipliers are also presented.
