Description

technical field [0001] The invention belongs to the field of integrated circuit design, and in particular relates to a dual-core ARM SoC computer FPGA reconfiguration system and an operation method. Background technique [0002] With the upgrade of various missile weapon systems in terms of range, maneuverability, combat deployment capability, and function changeability, missiles generally have higher and higher requirements for the miniaturization, localization, and high maintainability of the control system. In previous designs, computer circuits built with imported components could not meet the development trend of localization of missile systems due to the great restrictions on components due to the embargo or sanctions. The localized computer based on dual-core ARM SoC is adopted, and all the components in the computer are realized by domestic components, so as to satisfy the independent controllability of the product and avoid being affected by various unstable factors...
