| 摘 要： | 在新一代综合航电系统中,由于传统总线传输上的"瓶颈"问题,使得1553B总线远远满足不了系统信息传输的要求,可变规模相干接口(SCI)的出现,弥补了传统总线技术的不足,大大提高了信息交互的效率和带宽,满足了系统中和系统间的互连要求,成为先进互连技术的代表,其低延迟高带宽的特点完全可胜任各种关键应用领域.给出了一套完整的基于确定与随机Perei网的可变规模相干接口建模和性能分析算法.通过解决SCI性能评估建模的问题,进而得到系统吞吐量与延迟时间之间的关系.

| Abstract: | In the new generation of the integrated avionics system,the 1553B bus cannot meet the requirement of data transmission because of the traditional transmissionbottleneck.However,with the development of Scalable Coherent Interface(SCI),information exchange efficiency and bandwidth have been greatly improved,as a result,satisfying the connecting requirement and being the representative of the advanced interconnecting technology,which can be applied in various key fields because of its low latency and wide band... |
