Miniature integrated avionics core processor

The invention discloses a miniature integrated avionics core processor, and belongs to the field of airborne avionics systems. The processor comprises a case, an input and output module, an optical fiber bus module, a filtering power supply module, a core processing module, a storage module and an expansion module which are in communication connection in sequence are arranged in the case, and the core processing module is further connected with the optical fiber bus module, the filtering power supply module, the input and output module, the storage module and the expansion module through a backboard circuit. The input and output module is connected with each peripheral subsystem through a built-in unified optical fiber bus, and the core processing module adopts a T1042 multi-core processor with a PowerPC architecture. A high-density and small-size modular structure is adopted to form a low-cost compact distributed system, the system has the advantages of being low in coupling and easy to expand, an embedded m
