FPGA Secure Remote Update and Fast Online Reconfiguration Technology for Aerospace Equipment
In order to solve the problems of remote update of field programmable gate array (FPGA) after assembly and fast multi-mode switching during on-orbit operation in aerospace equipments, a secure remote update technolo-gy of FPGA based on fast startup and a fast online reconfiguration of FPGAs using internal configuration access port (ICAP) are realized. Through the handshake mechanism of file transfer, multiple verification of data, and the design of key switchwords in Flash, the security and reliability of remote update of the image are ensured. ICAP is used to send warm boot jump sequence and internal PROGRAM (IPROG) command, the fast online reconfiguration of FPGA is realized. The experiment verifies that several FPGA devices can be updated remotely and reconfiguration online at the same time, and can still run the old version and remote update again when the update fails, which improves the development efficiency of aerospace equipment and enhances the safety and reliability of system operation.
