基于FPGA的AFDX软硬件协同设计

AFDX HW/SW Co-Design Based on FPGA

随着目前民用大型飞机的国家战略实施,针对大飞机航电系统中骨干网络AFDX,提出一种基于FPGA的AFDX端点卡.该方案基于软硬件协同设计的思想,设计出一种新型的基于PCIE接口或基于SoPC的AFDX端点卡.基于FPGA的AFDX端点卡成果可直接应用在军用大型运输机、直升机、战斗机、机场地面维护系统等平台上,可以提升军用计算机的高安全、高可靠性能.为各类武器平台电子设备的开发提供相关标准和规范,可以缩短系统开发周期,降低系统开发成本.

With our national strategy implementation involving large civil aircraft, AFDX endpoint card based on FPGA is proposed, which is specific to AFDX backbone network of large aircraft avionics system. Based on the thought of HW/SW co-design, the programme designs a new type of AFDX endpoint card with PCIE or SOPC interface. AFDX endpoint card based on FPGA can be directly applied in such platforms as large military transport aircraft, helicopters, fighter jets, airport ground maintenance system and so on and can enhance safety and reliability of military computer. What’s more, development process will be accelerated and the cost will be lowed by offering related standards and specifications for electronic equipments of different kinds of weapon platforms.
