Design and Improvement of Host and Backup Selection
In order to resist the Single Event Upset（SEU）in outer space so that the camera focal plane array system could work in a long time, a design and improvement method for the selection of host and backup based on FPGA was introduced. VHDL was used to do the design and simulation, FPGA developed by Altera company was chosen as the hardware design platform. The results of experiment showed that the improved module could reliably get a group of effective data from the two in all cases and the camera focal plane array system could produce reliable driving timing for the CCD camera.
