Parallel optical logic processor and bit slice-full adder using a single electron trapping device

摘要

A new method is proposed for implementing logic operations by using a single electron trapping (ET) device. Based on the storage and erasure characteristics of the device, each Boolean logic operation can be performed by the corresponding programming. The encoding method is efficient, since each bit is spatially encoded by a single pixel. The system is simple and the optical elements can be stacked together, so the structure is compact. Furthermore, the logic operations involving three or even more variables can be realized easily with the suggested architecture. All the operations are executed in parallel. As an example, a triple-in binary logic processor is demonstrated to perform bit-slice full additions. Experimental results are given. (C) 1998 Elsevier Science Ltd. All rights reserved.
