Abstract

We will discuss a new optical parallel- arithmetic processing scheme that uses a nonholographic optoelectronic content-addressable memory (CAM). To increase the processing speed, a carry look-ahead addition (CLA) scheme can be used. We will also present the design of a 4-bit CAM-based optical-carry look-ahead adder, as well as our experimental results.
