DOT/FAA/AR-07/39, REAL-TIME OPERATING SYSTEMS AND COMPONENT INTEGRATION CONSIDERATIONS IN INTEGRATED MODULAR AVIONICS SYSTEMS REPORT (AUG 2007) (FINAL REPORT)., The combination of rigorous development assurance and verification assurance has led to safe and reliable operation within civil aviation systems and equipment. Historically, such systems were designed as federated architectures, yet significantly successful efforts in integrated modular avionics (IMA) system integration have occurred, such as the Boeing 777 aircraft. This technical report can be used to formulate a basis for evaluating the integration of real-time operating systems (RTOS) and other associated modules that support partitioning in space, time, input/output, communications, and other shared resources on an IMA system. Several role players (platform supplier, RTOS supplier, application supplier, and the IMA system integrator) in IMA system development are discussed, and their roles of integrating multiple functions at different integration stages are detailed.
