Abstract : Research was carried out on an electro-optical bound document scanner which used a general purpose F-8 microcomputer as the scanner controller. The goal was to replace the F-8 with a dedicated controller by replicating essential features of the system which provided the scanner/controller interface. A microprocessor-based configuration was considered to be the most promising approach. A detailed analysis of the existing hardware and software interface between the F-8 and the scanner was conducted to establish the feasibility of using a microprocessor and to develop controller design criteria. Features of a number of microprocessors were examined and compared against one another to determine the best architecture for this application.
