Address mapping and the control of access in an interactive computer

Abstract

Computer system designs have attempted to maximize machine utilization (sometimes called efficiency) without regard to other important factors including the human effort and elapsed time required to solve problems. In recent years some computing systems have been developed which provide communication and control means by which users can interact with their own computing processes and with each other. Initial use of these systems has demonstrated their superiority in computer-aided problem solving applications. These interactive computing systems are mainly adaptations of conventional computing systems and are far from ideal in many respects. This paper describes a much improved mechanism for protection, address mapping, and subroutine linkage for an interactive computing system.
