Design method and system for space-borne FPGA preventing space environment influence

Abstract

The invention relates to a design method and a system for space-borne FPGA preventing space environment influence, comprising XIL INX FPGA, ACTEL FPGA and PROM. Sum check is carried out to configuration files by ACTEL FPGA, and configuration files of XIL INX FPGA to ACTEL FPGA by JTAG port are read. Once an error is discovered during the sum check, loading is again carried out to configuration files of XIL INX FPGA that overturning by autonomously control PROM, so that correctness of configuration files in XIL INX FPGA is guarantied. Occurrence of single particle event can be rapidly detected by adopting the method, and influence caused by the single particle event can be lowered to lowest. The design method has been verified in information processor of FY-3satellite data transmission subsystem.

Description

technical field [0001] The invention relates to a space-borne FPGA, more specifically, to a space-borne FPGA design method and system for preventing the impact of the space environment. Background technique [0002] my country's new-generation polar-orbiting meteorological satellite Fengyun-3 is my country's second-generation polar-orbiting meteorological satellite, which is used to achieve global, all-weather, three-dimensional, quantitative remote sensing. The information processor of the digital transmission system mainly completes the functions of format arrangement, data encryption, scrambling and encoding of multiple satellite payload data, and is one of the core stand-alone satellites. The orbital altitude of the satellite is about 830Km, and the space environment is relatively harsh, especially the influence of single particles is more prominent. The main function of the information processor is realized by XILINX FPGA. Due to the problem of the production process o...
