Abstract:

This is a final report on the implications of associative memories to naval systems. Summarized briefly are three specific applications comparing the utility of a Hardware Associative Memory HAM versus a logically equivalent but slower multilist technique usable on any computer. The applications were 1 pattern recognition for bubble chamber pictures 2 maintaining a Sea Surveillance file as part of a large data system and 3 weapon assignment similar to that used in the Naval Tactical Data System. This report also describes in considerable detail an associative memory integrated into the design of an otherwise conventional computer. Order codes, block diagrams, etc., are given. A thin film memory is postulated both for the associative memory itself HAM and also for other uses. The feasibility and estimated costs of plated wires for this film memory have been investigated. The use of an associative memory by an executive routine is very promising, e.g., an order of magnitude improvement in mass storage throughput. Several fast memories currently under development have a NonDestructive Read Out mode NDRO such memories can be given inexpensive associative functions for the programmer to use optionally. Author
