Abstract

Previously, we showed experimental results using spatial light rebroadcasters (SLRs) for orthogonal associative memory and for key word addressable memory. The SLR is suitable for memory because it may be written and then read later. In this paper, a parallel set of half adders is constructed using a single spatial light rebroadcaster together with an image intensifier and optically addressable liquid crystal light valve (LCLV). Experimental results using a 10 X 10 array show 100 additions in one step. We describe how to construct a parallel ripple-carry full adder and a bit-slice full adder with a single half adder.
