Using Type Extension to Organize Virtual Memory Mechanisms

Abstract

Much effort is currently being devoted to producing systems that are easy to understand, to verify and to develop. The general methodology for designing such a system consists of decomposing it into a structured set of modules so that the modules can be understood, verified and developed individually, and so that the understanding/ verification of the system can be derived from the understanding/ verification of its modules. while many of the mechanisms in a computer system have been decomposed successfully into a structured set of modules, no technique has been proposed to organize the virtual memory mechanism of a system in such a way.
