Because of the tremendous growth in the terminal-oriented users community, software text editor is increasingly becoming a significant overhead for the computing systems. The files being manipulated by text editors are usually small but undergo rapid growth and development in its short-lived life-cycle. A look into the basic command structure of these text editors reveal that the operations performed by them fundamentally consist of pattern matching, pattern transformation, pattern deletion and insertion, and management of a set of counters and pointers. It is proposed in this paper that a specialized front-end processor with built-in string processing hardware provide a natural solution to the problem. This paper presents a possible architecture and logical capabilities of such a machine as an embellishment of microprocessors to be used for intelligent terminals. In the process, the structure of a general purpose non-numeric processor is evolved.
