随着高新技术的不断发展，航空电子机载系统能支持越来越复杂的功能，当前的综合模块化航空电子（IMA）系统架构采用模块化的设计以及开放式的架构，在提高航空电子系统可靠性的同时大大降低了功耗及成本。但随着飞行任务的日益复杂以及机载系统功能的不断增加，当前的IMA系统在面对复杂的应用需求时出现了无法突破的技术瓶颈。基于当前IMA系统的技术瓶颈，详细描述了下一代IMA系统的架构设计细节，总结了实施下一代IMA系统将面临的技术挑战，从高速网络，高性能多核处理器以及多核虚拟化等方面分析了有望发挥重要作用的关键技术，并提供了关键技术可行的研究思路，为下一代IMA系统的相关研究提供参考。

With the continuous development of high-tech, avionics airborne systems can support the increasingly complex functions. The current integrated modular avionics（IMA） system adopts modular design and open architecture, which improves the reliability of avionics and greatly reduces cost. However, with the increasing complexity of missions and the increasing functionality of airborne systems, current IMA systems have experienced unbreakable technical bottlenecks in the face of complex application requirements. Based on the technical bottleneck of the current IMA system, the architectural design details of the next-generation IMA system are described, and the technical challenges that will be faced in implementing the next-generation IMA system are summarized. From the perspective of high-speed networks, high-performance multi-core processors and multi-core virtualization, key technologies with an important role are analyzed. It also provides key technically feasible research ideas and provides reference for relevant research of the next generation IMA system.
