一种高速串行的FPGA间数据传输方法

A high-speed serial data transmission method among multiple FPGA chips

针对多FPGA芯片验证系统中FPGA端口资源有限的问题,提出了一种基于AXI总线协议的多FPGA片间总线传输方法。首先将所需传输的数据整合到AXI总线上,然后采用高速串行总线对数据进行传输,最后搭建FPGA的原型验证平台,通过vivado软件对传输数据进行分析,实现了多片FPGA间数据的高速传输。该方法不仅克服了FPGA原型验证系统中I/O端口有限的瓶颈,而且可支持任何厂家的FPGA片间传输,具有很强的工程实践性。

Based on the problem of the limited FPGA port resources in multi-FPGA chip verification system,this paper proposes a bus data transmission method based on AXI.First,it integrates the data to be transferred into the AXI bus.Then the high-speed serial bus is used to transmit the data.Finally,by building FPGA prototype verification platform and analysing transmission data using vivado software,this method realizes the fast transmission of data among multiple FPGA chips.It can not only overcome the bottleneck of limited I/O ports in FPGA prototype verification system,but also can support FPGA inter-chip transmission of any manufacturer.At the same time,it has strong engineering practicality.
