Abstract:

This work is related to a previous study, in which the intelligence retrieval application and data bases at FTD were analyzed potential usefulness of reconfigurable arrays and associative memories was assessed and an exploratory model of an associative unit was designed, fabricated, and evaluated. The work performed under this effort extended the analysis, acquired additional data and developed and demonstrated a full scale advanced document retrieval system. Models were developed for text compression, data base partitioning trade-offs were made, and analysis was performed for automatic data base generation. The work included the design and fabrication of a full scale associative processing unit AU with 1000 MOPS processing capability and 256K-bit storage capacity. This was interfaced to an array of three existing Advanced Flexible Processors AFP, a host computer, and a secondary mass storage system. This equipment configuration served as the hardware basis for the document retrieval demonstration.
