A decentralized Integrated Modular Avionics (IMA) architecture configured for onboard avionics processing eliminates centralized computing cabinets and distributes avionics processing capabilities to a network of smart switching devices positioned throughout the aircraft, each smart switch including a multicore processing environment (MCPE) for generalized application hosting in addition to the switching elements. The smart switching network can be scaled up or down for smaller or larger aircraft, or organically grown by adding more processing components. Additional real-time multicore processors may be located in smart remote data concentrators (RDC) for handling I/O and routing of network data between external remote units and aircraft systems and the hosted applications on the smart switches. The real-time environments executing on the smart RDCs may be reserved for low-latency closed-loop functions, or may host additional general-purpose avionics processing.
