| Abstract: | A new fault-tolerant method by ISP partial reconstruction is proposed, which can obviously reduce the reconfiguration data. The principle, arithmetic and characteristics of the new faulttolerant method are described. In order to remove obstacle in the implement of the new faulttolerant method, a new de-coupling circuit design method is presented. Tile new fault-tolerant method was employed in the telecommand data processing circuit for deep space exploration, and the implement process was demonstrated through Flash FPGA. |
