摘　　要：针对传统并行总线的嵌入式系统,信息交换及数据采集已不能满足高传输带宽、大数据交互的要求,提出了一种基于VPX(VITA46)架构下高速串行总线的高速数据采集系统设计方案。该系统满足VITA64标准,设计利用多片FPGA的GTX高速接口实现接口之间的连接与数据交互,采用Rapid IO、PCIE总线的双余度交互式结构,解决了传统并行总线接口类型多、结构复杂、协议转换的问题,并实现了数据的高速交互,提高了系统高可靠性。结果显示,平台大幅提高了传输带宽,其中Rapid IO总线单通道传输速率可达6.25 Gbps。此外,重点介绍了平台的基本原理设计、设计过程中采用的关键技术等。实验结果表明,该方案具有通用化、扩展性高、可靠性高等特点。实际工程验证,设计的平台能达到高传输带宽、大数据交互的要求,同时该系统的性能优越,功能稳定可靠。In view of the traditional parallel bus embedded system,information exchange and data acquisition can not meet the requirements of high transmission bandwidth and big data interaction,a high-speed data acquisition system based on VPX(VITA46)architecture is proposed in this paper.The system meets the VITA64 standard.The GTX high-speed interface of multiple FPGA is designed to realize the connection and data interaction between interfaces.The dual redundancy interactive structure of Rapid IO and PCIE bus is adopted to solve the problems of multiple interface types,complex structure and protocol conversion of traditional parallel bus,and realize high-speed data interaction.This improves system reliability.The results show that the platform greatly improves the transmission bandwidth,among which the single channel transmission rate of the Rapid IO bus can reach 6.25Gbps.In addition,this paper mainly introduces the basic principle design of the platform and the key technologies adopted in the design process.
