COMMON INTFGRATFD PROCFSSING IN MODUI AR AVIONICS

This paper presents a review of the current modular avionics concepts and discusses a powerful processing system, the Hughes Modular Processor, developed to meet the objectives defined from those concepts. This paper also discusses future trends in avionics into the next century along with how modular avionics will impact the way the equipment developers interact. Current modular avionic concepts are reviewed as embodied in our advanced avionics systems. Initially mandated because of the perceived cost advantages, modular avionics also provide significant performance potential. A key characteristic of modular avionics is the partitioning of the system into highly integrated, common and modular building blocks. The partitioning features are defined and rationale presented on the approach taken.
