摘　　要：国外对AFDX网络核心产品的垄断严重制约了我国AFDX网络技术的发展,难以建立完整的AFDX网络产品体系。提出了一种基于自研AFDX网络端系统芯片的模块设计方法,从软硬件设计角度阐述模块的设计与实现过程。该模块集成端系统SoC芯片,具有PMC、PCI和CPCI三类主机接口,完成AFDX网络数据通信功能。目前已成功应用于型号工程,其功耗低,功能、性能稳定可靠,国产化率高,具有较高的成熟度,打破了国外产品垄断,实现了AFDX端系统模块的自主保障、自主可控。Because of monopolizing AFDX network core products, which seriously restricts the internal development of AFDX network technology. At the same time, the establishment of AFDX network product system integrity is a laborious effort. This paper provides the method of the module design of AFDX network end system chip. The end system module ′ s design and implementation process are based on combining of hardware and software. This module is embedded with end system So C chip and provides PMC,PCI and CPCI host interface that it implements the AFDX network data communications. This product has been successfully used in the model project. It has many advantages, such as low power consumption, stable and reliable function, high domestic rate and high maturity. It breaks the monopoly of foreign products and realizes autonomous protection and autonomous control of AFDX net-work end system module.
