This invention, belonging to the field of onboard intelligent information processing, discloses a method for loading, refreshing, and on-orbit reconfiguration of an FPGA in an onboard real-time information processing system. The system comprises five components: a power supply unit, a measurement and control and configuration management unit, an interface unit, an image processing unit, and a busbar backplane. For an onboard real-time information processing system based on a dynamic redundant architecture, this method proposes a parallel architecture that combines a configuration management FPGA with Nor Flash, NAND Flash, SDRAM memory, and multiple SRAM-based FPGAs. This allows for simultaneous loading and refreshing of multiple SRAM-based FPGAs, improving loading efficiency, shortening on-orbit reconfiguration time, addressing potential hidden path risks in the system, streamlining system size, and improving system cost-effectiveness.

The application relates to the field of Internet of Vehicles edge computing, and discloses a high-performance real-time information processing system supporting Internet of Vehicles streaming computing, which comprises a vehicle-mounted terminal, a source node and a target node. The vehicle-mounted terminal generates a split mark containing a motion trajectory signature when entering an overlapping coverage area and appends the split mark to a service data stream for transmission. The source node extracts an accumulated state according to the split mark, generates state algebra fragments and state gradient information, and encapsulates the state algebra fragments and the state gradient information into a single frame control packet consistent with the inner five-tuple of the service data stream. The target node card compresses the service data and the control packet into the same hardware receiving queue through hashing. A computing engine performs verification in combination with the motion trajectory signature, and performs delay compensation according to the state gradient information. The five-tuple is modified to uniformly distribute the hardware queue to avoid memory lock competition, the replay attack is blocked in combination with the physical motion characteristics of the vehicle, and the transmission time delay is corrected by using the gradient compensation, so that the safety and accuracy of the state handover between nodes are guaranteed.
