This paper introduces an integrated modular avionics core system. First, based on the analysis of system application requirements and technical characteristics, a general open architecture model is pro- posed, and the key technology of the system is deeply studied, including system management, network communication, time synchronization, fault- tolerant strategy, and finally the recommendations of the sys- tem design scheme. The system has the reconfiguration, reusability, scalability and robustness, can meet the application requirements of advanced aircraft avionics system, and provides technical support for the research and design of new distributed integrated modular avionics system.
