The design on SEU-tolerant information processing system of the on-board-computer

Abstract

For SEU(Single-Event-Upsets) of space radiation environment, a multi-level fault-tolerant mechanism based-on FPGA, which has greatly improved the system's ability of resisting SEU was presented. The design of three-level fault-tolerant included the dual fault-tolerant system based-on FPGA, the module-level triple modular redundancy, and the chip-level SEU-tolerant FPGA. Finally, the evaluation for the SEU reliability of the OBC(on-board-computer) was mentioned. © Springer-Verlag Berlin Heidelberg 2007.
