摘　　要：针对同时满足高速的A/D采集、高速率的数据传输和实时显示且便于携带实际应用需要,研究设计了基于FPGA+ARM的实时数据采集的嵌入式平台。采用FPGA控制A/D完成高速数据采集,通过串口总线实现了平台内部FPGA和ARM之间指令的下达和数据的上传,最终实现在ARM上通过Qt应用程序对A/D采集的数据进行实时显示。Aiming at meeting the actual application needs of the high-speed AD sampling,high rate data transmission and real-time display and portable,a real-time data acquisition based on FPGA＋ARM embedded platform is researched and de-signed,which uses FPGA controlled AD to realize high speed data acquisition,the internal instruction issued and data upload between FPGA and ARM is achieved by serial bus. Finally the real-time display of the data collected by AD is realized on the ARM by Qt application.
