Abstract


In the past 10 years of China Aerospace, FPGA has been widely applied to electronic systems of spacecraft as Digital Signal Processing, image processing and other tasks in space environment, because of its functional diversity and repeatability, mass data processing flexibility and efficiency. The Xilinx Virtex series FPGA(SRAM technology)is better than others in the performance and capacity,and can be reconfigured according to the different requirements.However, SRAM FPGA is influenced heavily by the space radiation. The logic value of internal configuration memeory often upsets because of the high-energy particles hit(SEU). SEUs may result in Spacecraft s information lost or function interrupt. Becsuse of the speciality of space environment, the reliability is being the importment target of spacecraft and the design of tolerance is necessary in electronic systems of spacecraft.Based on some 863 project, the three significant technologies including configuration, scrubbing, readback are deeply studied in this thesis. Based on this, two fault-tolerance methods of SRAM FPGA, the open-loop solution based on scrubbing periodly; and the close-loop solution based on readback, comparison and scrub, which this paper focuses on, use antifuse FPGA for Virtex-II configuration and fault-tolerance, cooperate with Triple Modular Redundancy design of Actel and Xilinx. FPGA is configured by slave SelectMAP mode,by which the fault-tolerance methods are implemented. User could make a little change to transplant these methods to other electronic systems of spacecraft.This paper also make research on resource consumption, scrubbing rate, readback rate and the evaluation methods of fault-tolerant effect.This research has actually applied to two 863 projects and a major national science and technology projects, as their fault-tolerant solutions of SRAM FPGA. Combined with fault-tolerant effect of future evaluation of the program, it affords a good reference for our high reliability electronic systems of spacecraft.
