Over the past decade, much of the research in the areas of fault tolerant computing and reliability analysis has been performed relative to flight control, space vehicle guidance, propulsion control, and similar applications. Since 1978, the Flight Control Division of the Air Force Wright Aeronautical Laboratories Flight Dynamics Laboratory (FDL) has been involved in in-house research into fault tolerant multiprocessor flight control systems. The emphasis of these studies have been on applying microprocessor technology, dynamic sparing, and distributed parallel processing techniques rather than the conventional triple or quadrupole channel computer structures. This paper will discuss the pertinent issues, systems, and concepts leading up to the current work on the Advanced Multiprocessor Control Architecture Definition (AMCAD) program. Included will be a summary of the benefits and problems associated with the key concepts of the CRMMFCS architecture developed by the FDL from 1980-83.
