An Implementation of Multiprogramming and Process Management for a Security Kernel Operating System.

This thesis presents an implementation of multiprogramming and process management functions for the security kernel of a distributed multiprocessor system. The implementation is based on a family of operating systems designed to provide controlled access in a microcomputer network to data bases containing multiple levels of sensitive information. Multiprogramming improves system efficiency and creates a virtual environment which frees the remainder of the operating system from a dependence on processor configuration. Processor management coordinates the asynchronous interaction of system processes. This implementation describes a processor multiplexing technique for distributed kernel and presents a virtual interrupt mechanism. Its structure is loop free to permit future expansion into more complex members of the design family. Author
