Abstract

During the past few years, considerable attention has been focused on the hardware aspects of both large and small associative memories and associative memory processors (AMP). 1,2,3,4,5,6,7,8,9,10 Additionally, very small associative memories have been included in computer systems for specific functions. 11,12 Several investigators 13,14,15 have reported on the effectiveness of AMPs for applications in which the data base was small enough to fit entirely in the associative memory, or in which the data stored in the associative memory changed infrequently. The purpose of this paper is to summarize the major findings of a study of associative memory processors added to a general purpose computer (to comprise a hybrid associative processor) in dealing with a data processing application involving a large data base. The study considered alternative AMPs in query processing, file maintenance, and in certain system executive functions. Since the specific results of the study are applicable to only one class of problem, this paper presents the results in such a way as to show the major considerations one will have to deal with in determining whether a hybrid associative processor will prove advantageous for a specific problem.
