Common integrated processing in modular avionics

The authors present a review of the modular avionics concepts and discuss a powerful processing system, the Hughes modular processor, developed to meet the objectives defined from those concepts. They also discuss future trends in avionics into the next century along with how modular avionics will affect the way equipment developers interact. Current modular avionic concepts, as embodied in advanced avionics systems, are reviewed. 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 the rationale for the approach taken is presented. The Hughes modular processor family of imbedded avionics processors has been shown to be a powerful and innovative realization of the application of modular avionics concepts to the core avionics
