RapidIO User-level Communication Interface Realization Based on RDMA
基于RDMA的Rapidl0用户态通信接口实现

As a high performance interconnect protocol in embedded system,RapidIO promises a better performance by taking advantage of Remote Direct Memory Access operations. At present, the only accessible RapidIO communication interface is Ethernet simulator, which limits the communication performance of RapidIO. In accordance with the characte-ristics of RapidIO protocols,this paper put forward a RapidIO user-level communication interface based on RDMA by making reference to the various methods of communication protocols based on RDMA at home and broad. After that,the author validated the performance of this communication interface, and made its implementation to achieve optimizalion through various ways. I3y comparison, this RapidIO user-level communication interface is known to gain the highest throughput in all the present Rapidl0 communication interface.
