Abstract:

This thesis presents an implementation of process management for a security kernel based secure archival storage system SASS. The implementation is based on a family of secure, distributed, multi-microprocessor operating systems designed to provide multilevel internal security and controlled sharing of data among authorized users. Process scheduling is effected by one half of a two level Traffic Controller that binds processes to virtualized processors. Inter-process communication mechanisms for synchronization, mutual exclusion, and message passing among processes are provided by utilization of eventcount and sequencer primitives. The implementation structure is based upon levels of abstraction and is loop free to permit future expansion to more complex members to the design family. Implementation was completed on the ADVANCED MICRO COMPUTERS Am 964116 AmZ8002 16 Bit Monoboard Computer.
