Evaluation of Three Content-Addressable Memory Systems Using Glass Delay Lines

摘要

Evaluation is made of three content-addressable (associative) digital memory system organizations using a circulating memory. Specific reference is made to glass delay-line memories since they offer the best solution to high-speed circulating storage. The memory designs are each developed as a possible memory addition to the NEBULA Computer at Oregon State University. A useful command set is established along with a discussion of applications of such a memory system. Then the three separate data organizations are explained and the logical design and hardware requirements for each system type are detailed and compared. A circulating memory is utilized because it allows very inexpensive implementation of content-addressing capability. (Author)
