Communication performance analysis of Scalable Coherent Interface
Zhang Jiandong, Min Pang, Yong Wu, Shi Guoqing · 2011
In the designing process of the integrated avionics system, the bus system performance is closely related to the overall index of the entire avionics system. Scalable Coherent Interface (SCI) possesses some advantages, such as low latency and high bandwidth, and it can also meet the interconnection requirements within a system and between systems, which makes it applicable to various key operations. This paper researches the SCI multi-ring simulation problem. It starts from the SCI protocol, and uses Petri nets as a tool to establish an exchange unit model and the system model. At last it is found that the simulating and solving of the system model can derive the relationship between system throughput and delay time.
