A Microprogrammed Search Controller for a Text Scanning Processor

Abstract

The objective of the research in this paper is the design of a non-numeric processor to be used in the scanning of textual information brought in from serial storage. Source text progresses through a linear array of 32 cells each cell capable of holding one character. With all cells operating in parallel, character subsequences in the source stream can be compared with character strings in any one of 16 registers associated with the cellular array. Various modules associated with the array are used to aid the query resolution process. The overall design emphasizes speed of execution and versatility of operation.
