| Abstract: | The FPGA is more and more being applied to space and air information system currently,while the SRAM-based FPGA is a kind of electronic components which is more impressionable to space radiation effection.For raising the credibility of SRAM-based FPGA,a fault-tolerant system designing method based on FPGA dynamic partial reconfiguration is proposed.Through in-depth analysis of the failure mechanism of FPGA,this paper compares different fault-tolerant methods,combines the advantages of Dynamic Partial Reconf... |
