Abstract: This paper presents the scheme to implement the bridge between VMEBus and CPCI using Universe II from Tundra Company. It also introduces its characteristic, applications and working principle. Meantime it discusses how to port the bridge driver and deal with the problems in the debugging. The experiments show that the developed backplane with the CPCI-VME bridge is practical.
