Real-time, Ada-based, avionics processing

It is noted that next-generation, embedded avionics systems are demanding an order-of-magnitude higher performance, faster responsiveness, information security protection, and configurable components to deal with the exploding information content modern battlefields. They require customizable reusability and a high degree of programmability to keep pace with rapidly changing tactical environments. Architectures which seek to satisfy these demands use multiple embedded controllers, RISC (reduced instruction set computer) processors, cached memories, and programmable signal processors. They rely heavily on embedded Ada runtime technology to meet their goals. The authors describe a RISC-based multiprocessor architecture and associated Ada operating system that support these next-generation avionics concepts while providing enhanced system integrity and information security support features
