摘要
SCI(ScalableCoherentInterface,可扩展的一致性接口)协议是一种应用于计算机集群互联的总线协议,为新一代战机航空机载光纤数据总线重点的备选考虑之一。SCI协议具有很低的延时、很高的数据吞吐率、良好的扩展性及一致性。基于此,分析SCI协议中传输事务、对列分配、带宽分配、传输错误处理、缓存一致性等子协议。
SCI（ Scalable Coherent Interface ）standard is a kind of cluster interconnection bus standard. It has been select as an important candidate for the new generation avionics data bus. It has low latency, high throughput and good scalability. To gain such goal, SCI uses register insert ring structure and uses distributed control methods. SCI standard is complex as a whole. This paper is going to analyze the transaction model, queue allocation, bandwidth allocation, transmission error handle and cache coherent sub-protocol of SCI standard.
