摘　　要：本文在分析知识库系统和光计算特点的基础上 ,提出了基于光计算的知识库系统 (KBSBOC)模型及其硬件支持系统 ,KBSBOC采用二进制矩阵表示知识 ,并用矩阵计算来实现并行推理和学习 ,这使知识库操作全并行化 ,适合于光计算。KBSBOC硬件支持系统是光电混合系统 ,主要由主控机、知识存储体及光并行逻辑运算器构成。性能分析和实验结果表明 KBSBOC及其硬件支持系统是有效的、合理的 ,它使解决迷宫问题的时间复杂性压缩到 O(n)。This paper,based on the analysis of the features of knowledge base system and optical computing,proposed a knowledge base system based on optical computing (KBSBOC) and its hardware support system.The KBSBOC adopts a binary matrix knowledge presentation,and performs the parallel inference and learning by matrix operation,which makes the knowledge base operations become full parallel operations and suitable for optical computing.The KBSBOS hardware support system is opto electronic system and was composed of main control machine,knowledge storage unit and optical parallel logic arithmetic unit.The performance evaluation and experiments show the KBSBOS and its hardware support system are valid and reasonable,and the system can make the time complexity for solving Maze problem reduce to O(n).
