Research and Design of On-board Dynamic Reconfigurable Router

In order to satisfy the requirement of aerocraft´s multi-transmission for further development, the paper leads to a resolution about on-board dynamic reconfigurable Spacewire routing technology. Based on the network level analysis of Spacewire standard, it built the architecture of router with wormhole routing theory. A simulation model of router had been set to verify the design, and braking-problem from wormhole routing-blocking had been solved with BWR. And a prototype of dynamic reconfigurable router had been built by using the characteristic of high-speed processing and dynamic reconfiguration of FPGAs.
