The invention discloses a four-core flight control computer based on dual-SoC architecture SiP modules. The overall structure and function framework of the flight control computer are optimized, and two dual-SoC architecture SiP modules are used to substitute a large amount of independent packaging electronic components to build a traditional flight control computer core control circuit. The modular design idea is employed, and the whole flight control computer comprises a control module, a time sequence module, and a power distribution module. The aircraft navigation, guidance and attitude control calculation, initiating explosive device regulatory agency working state acquisition, switch amount and voltage amount measurement, time sequence control, power distribution control, bus scheduling, communication management, information storage and the like can be completed. According to the four-core flight control computer, the design difficulty is reduced, the development cycle is shortened, the stability and integration are improved, and the four-core flight control computer has an important significance for the promotion of the integration, modularization, generalization, light and standardization of the flight control computer and the improvement of the performance of a flight control system and the operational performance of an aircraft.
