Abstract: This paper proposes a new method to realize RapidIO user-level communication interface based on Transparent Inter Process Communication(TIPC).Through the analysis of the characteristics of RapidIO message passing mode and the mechanism of bottom send and receive realization of TIPC,the data memory copy times of the sender and receiver are both reduced to one,which greatly expands the throughput and depresses the communication latency of RapidIO communication interface.
