光学脉动进位多比特全加(减)器

Optical Ripple Carry Multi-bit Full-adder(Subtractor)

本文提出了一种利用光学符号代换法则和脉动进位原理实现进位超前的光学多比特全加(减)器,其特点是不需要任何实时器件来存储中间结果,所以结构简单、速度快,并且可以实现由多比特二进制数所组成的矩阵间的加(减)法。

In this paper, wepropose a kind of system which based on optical symbolic substitution rule and ripple carry propagation principle to implement look-ahead optical multibit full-adder (subtractor), The characteristic is that it is of simple structure sad high speed for no inter-mediate results to be stored by any real-time device, and can implement multi-bit binary matrix addition(subtraction).
