This research is exploring the application of optical systems for high-speed database processing. It is combining a parallel model of computation, associative processing based on the use of content addressable memory, with an inherently parallel technology, optics. The purpose is to integrate into one study the elements of parallel architectures, parallel algorithms, device technology, and laboratory demonstrations which will test and demonstrate the advantages of optics for high-speed database processing. The approach taken on this project provides direct hardware support for database operations. It consists of identifying the basic fundamental operaitons required for data base processing and aprallelizing them as much as possible. This is followed by developing an optical parallel architecture that directly implements the parallelized operations. Parallel algorithms for database processing are then developed that build on these fundamental operations. Consequently, the optical architecture will support database applications in a truly parallel fashion.

这项研究正在探索光学系统在高速数据库处理中的应用。它结合了一种并行计算模型，即基于内容可寻址存储器的关联处理，以及一种固有的并行技术--光学。其目的是将并行体系结构、并行算法、设备技术和实验室演示的元素整合为一项研究，以测试和演示光学技术在高速数据库处理方面的优势。该项目所采取的方法为数据库操作提供了直接的硬件支持。它包括确定数据库处理所需的基本基本操作，并尽可能地使它们合法化。然后开发了直接实现并行操作的光学并行体系结构。然后开发用于数据库处理的并行算法，这些算法建立在这些基本运算的基础上。因此，光学架构将以真正并行的方式支持数据库应用程序。
