Abstract:

Two of the many problems confronting avionics developers today are the need to rapidly design, prototype, develop, and insert modern technology into avionics platforms and the need to support that technology under conditions where the pace of obsolescence is much smaller than the devices required service life. SYMVIONICS Complex System Information Fusion Tools CSIFT program is facing both of these issues. In this paper, we will present our findings and recommendations to-date as a case study of the goals, approach, and accomplishments of the program. The CSIFT program uses a Data Activated Operating System commonly referred to as a Distributed Blackboard, in the context of an offboardonboard information fusion application, to implement a version of the Information Dispatcher function of the USAFs Airborne Information Fusion Architecture AIFA. Our approach provides an efficient environment for prototyping and developing data oriented avionics applications. The CSIFT program addresses the technology obsolescence issue by our use of the Continuous Electronics Enhancements Using Simulatable Specifications CEENSS methodology. This methodology provides for rigorous requirements modeling and formal verification, and promotes the use of vendor neutral, tool neutral simulatable specifications for electronic designs.
