“…The short-word mode is the conventional memory organization. The long-word mode is equivalent to the bit-serial associative technique, Bit-serial associative processing has been implemented through the use of 2½D core search memory [78][79]. Goodyear Aerospace Corporation [80][81] developed a modular plated-wire implementation of a bit-serial associative processor which uses the so-called processor modules as basic building blocks.…”

A survey of the architecture of various associative processors is presented with emphasis on their characteristics, categorization, and implementation, and especially on recent developments. Based on their architecture, associative processors are classified into four categories, namely fully parallel, bit-serial, word-serial and block-oriented. The fully parallel associative processors are divided into two classes, word-orgamzed and distributed logic associative processors. Keywords and Phrases:Associative processors, computer architecture, categomzation, implementation, hardware, large-scale integration, fully parallel, bit-serial, word-serial, block-ormnted, distributed logic CR Categories: 3. 80, 6.22, 6.30, 6.31, 6.32, 6.33, 6.34 INTRODUCTIONAn associative processor can generally be described as a processor which has the following two properties: 1) Stored data items can be retrieved using their content or part of their content (instead of their addresses); and 2) data transformation operations, both arithmetic and logical, can be performed over many sets of arguments with a single instruction. Because of these parallel processing characteristics, associative processors have a much faster data processing rate than conventional sequential computers, and hence are more effective in handling many types of information processing problems such as information storage and retrieval of rapidly changing databases, fast search of a large database, arithmetic and logical operations on large sets of data, control and executive functions in large-scale computer systems, radar signal tracking and processing, and weather prediction computations. However, because of their relatively high implementation cost, associative processors are usually used in conjunction with standard sequential computer systems so that many required highspeed parallel processing tasks which cannot be effectively executed by sequential processors are performed by associative processors. Because of the rapid development of large-scale integrated-circuit (LSI) technology, the implementation cost of associative processors will be greatly reduced and it is anticipated that associative processors will be used more extensively for enhancing the performance of many special-purpose and general-purpose computer systems. Although there have been several papers providing either tutorials or literature surveys on associative processors [1-5], a number of new developments have not been described in any of the previous survey papers. In this paper, we will present a survey of the architecture of various associative processors, with emphasis on their characteristics, categorization, and implementation, and especially recent developments.
