A computer system organization which allows a program to specify a predetermined security level for other programs which it invokes, while at the same time being subject to security restraints placed on it either by a higher priority level invoking program or by the operating system. A plurality of ...

Maxwell C Gilliland, Burton J Smith, Gary L Ferguson: Concurrent task and instruction processor and method. Denelcor, O Rourke & Harris, October 21, 1980: US04229790 (123 worldwide citation)

A processor and method for concurrent processing of tasks and instructions are disclosed. The processor is basically a multiple instruction, multiple data stream (MIMD) digital computer that utilizes pipelining for control and function units, but avoids precedence constraint penalties. Task and inst ...

Marc Appell, Georges Lepicard, Philippe Hubert de Rivet, John J Bradley, Benjamin S Franklin: Protection of data in an information multiprocessing system by implementing a concept of rings to represent the different levels of privileges among processes. Compagnie Internationale pour l Informatique CII Honeywell Bull, Diller Ramik & Wight, December 4, 1979: US04177510 (117 worldwide citation)

Computer data and procedure protection by preventing processes from intering with each other or sharing each other's address space in an unauthorized manner is accomplished in hardware/firmware by restricting addressability to a segmented memory and by a ring protection mechanism.
