Abstract

Aiming at the change of task requirements during the period of laser communication payloads in orbit and the potential design defects of software, this paper puts forward a design scheme of software on-orbit dynamic reconfiguration for spaceborne “FPGA and DSP”. In the aspect of DSP, based on the hardware architecture of MRAM and "FPGA+DSP", under the instruction control of the load controller, the dynamic reconfiguration functions such as version switching and on-orbit update of spaceborne DSP software are realized. at the same time, the dual storage mode of PROM and MRAM is constructed, which realizes the basic version fallback function in the case of abnormal reconfiguration and ensures the reliability of on-orbit operation. In the aspect of FPGA, the anti-radiation read-back refresh circuit is used to complete the read-write operation of the program in the NOR FLASH chip, so as to realize the FPGA reconstruction and program read-back refresh, improve the anti-single particle overturning ability and ensure the reliability. The scheme has flexible function and high reliability and has been successfully applied in the project.
