摘　　要：针对嵌入式系统中的多FPGA配置问题,结合实际应用,设计了一种基于ARM、NAND Flash存储器和串口的多FPGA命令选择配置方案。该方案以含有4片FPGA的嵌入式系统为例,选用ARM作为主控芯片,使用超级终端输入配置文件选择命令,构建了基于TMS320C6A8168、XC3S400AN和NAND Flash的硬件平台,实现了根据设备的应用差别加载不同FPGA配置文件的功能。详细描述了系统的硬件构成、软件实现以及在TD-LTE无线综合测试仪表中的应用情况。与传统基于专用存储芯片的配置方法相比,该方案大大提高了多FPGA系统配置的灵活性,在通信电子领域具有一定的实用价值。Aiming at the Multi - FPGA configuration issue in embedded system and combining the practical applications, a Multi - FPGAcommand selection and configuration scheme based on ARM, NAND Flash memory and serial ports is proposed. With the example of theembedded system which contains 4 pieces of FPGA chips, ARM is selected as the main control chip, and Hyper Terminal is used to inputconfiguration file and select command, so a hardware platform based on TMS320C6A8168, XC3S400AN and NAND Flash is built, whichachieves the function that selecting different FPGA configuration file to load according to the difference from applications. The hardwarestructure, software implementation and practical application in TD - LTE wireless comprehensive test instrument are introduced at great length.Compared with the traditional configuration method based on the dedicated memory chips, the system greatly improves the flexibility of FPGAsystem configuration, thus it possesses certain reference value in electronic communication field.
