A high-accuracy fiber-optic array processor (FOAP) based on the algorithm of digital multiplication by analog convolution is proposed. The FOAP architecture is a local regularly interconnected processor that utilizes an array of identical all-optical elemental-processing lattice units, namely, an optical splitter, an optical combiner, and a binary programmable fiber-optic transversal filter. Various FOAP matrix multipliers are proposed for nonnegative and twos-complement binary arithmetic matrix-vector, matrix-matrix, triple-matrix, and high-order matrix operations. The overall performances of the FOAP matrix multipliers are compared with the time-integrating and space-integrating architectures and with the digital multipliers. Extension of the digital-multiplication-by-analog-convolution algorithm is also considered.
提出了一种基于模拟卷积数字乘法算法的高精度光纤阵列处理器(FOAP)。FOAP架构是一种局部规则互连的处理器,它利用了由相同的全光元素处理晶格单元组成的阵列,即光分束器、光合束器和二进制可编程光纤横向滤波器。针对非负和二进制补码二进制算术矩阵 - 向量、矩阵 - 矩阵、三矩阵和高阶矩阵运算,提出了各种FOAP矩阵乘法器。将FOAP矩阵乘法器的整体性能与时间积分和空间积分架构以及数字乘法器进行了比较。还考虑了模拟卷积数字乘法算法的扩展。
