With the continuous improvement of airborne computing platform capabilities, to address the issues of resource fragmentation, high software-hardware coupling, and difficulty in scheduling of heterogeneous resources in traditional airborne computing platforms, we propose a unified computing architecture oriented towards functional depth integration, along with a specific design implementation. The architecture achieves resource pooling and dynamic scheduling capabilities through hardware-software co-design, significantly enhancing the overall processing efficiency of the system. In hardware, a unified processing and high-speed interconnection system is constructed based on open architecture standards, with configurable heterogeneous accelerators to efficiently carry out multiple parallel computing tasks; in software, following the FACE (Future Airborne Capability Environment) standard, a service-oriented and modular software architecture is proposed, supporting embedded container environments, heterogeneous resource management, and distributed computing frameworks. The unified computing architecture has significantly enhanced the system’s integrated processing efficiency, providing robust support for the depth integrated applications of avionics.
