随着FC网络在新一代航空电子系统的广泛应用,FC节点机对主机接口的带宽要求越来越高,PCIe接口FC节点机成为设计主流。为了适应一个PCIe接口访问多个FC节点机的应用需求,本文提出一种基于PCIe交换开关的多路FC节点机设计与实现方法。该设计具有所需主机接口少,面积小,重量轻,功耗低和成本低的特点。经系统验证,满足机载应用环境功能和性能要求。 With the extensive application of FC network in the new generation avionics system, the bandwidth requirements of the FC node host to the host interface are getting higher and higher, and the PCIe interface FC node machine becomes the mainstream of the design. In order to meet the application requirements of a PCIe interface to access multiple FC nodes, this paper presents a design and implementation of multi-path FC node based on PCIe switch. The design has the required host interface less, small size, light weight, low power consumption and low cost. System verified to meet the airborne application environment features and performance requirements.
