%X In order to meet the needs of high-speed multiplexing of data in aerospace applications and space radiation, this paper presented a dynamic partial reconfiguration fault-tolerant technology applied in the SpaceWire router. Based on the analysis of SpaceWire bus standard network layer, it added HanMing coding to the cell matrix non-blocking routing to achieve correct one error and detect two errors. If there was more than one error, the single error cell would be reconfigured by triple-modular redundancy, it used which Partition Pin as transmission hub between static modules and dynamic modules instead of bus macro. At last, assessed and compared the resources and time delay of the router before and after the fault-tolerant. The experiment result demonstrates that, compared with three module redundancy for the entire cell matrix, the method can save hardware resource and reduce the delay time.
