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.
