Abstract:Fault-tolerant technique is a key way to improve reliability puter system, which is more and more
widely applied in design and development puters under on-board environment. An embedded resolvent of
the on-board information processing system based on COTS was presented and implemented. In allusion to
abominable environment, a multi-level fault-tolerant mechanism based-on FPGA, which has greatly improved
system’s reliability and stability, were implemented, by using Altera's EP1C6Q240C8 and EP1C4F400C8. In
addition, an abnormal-current-resisting protection circuit was designed with both chip-level and board-level's
detections. With reliability greatly enhanced to fit the need, the system was high-performance, low-cost and
small-volume.
