Abstract

An optical architecture called optical content-addressable parallel processor for relational database processing (OCAPPRP) for the high-speed processing of database operations based on a 2-D optical content-addressable memory (CAM). The architecture gained from enhancements resulting from novel methods in hardware and algorithm design. Since relational database operations can be divided into two types of searches, equivalence and relative magnitude, OCAPPRP performed both of these with maximum parallelism. Together with dealing with the improvements in search algorithms, the issue of parallel readout of the CAM was also addressed. To establish the viability of OCAPPRP, its optical implementation with existing optoelectronic components was presented.
