本文提出了基于ARM+FPGA的实时高数数据采集系统,利用AD5220对外界的模拟信号转化为数字信号,采用FPGA完成对高速数据的采集工作,通过ARM对FPGA的采集的数据进行处理,并且利用嵌入式Linux,通过对操作系统的操作来实现对FPGA进行实时的控制。本文首先介绍了系统的总体架构,然后介绍了系统中所需要的元器件,最后重点介绍了对FPGA模块驱动程序的初始化工作。 In this paper, real-time high-frequency data acquisition system based on ARM + FPGA is proposed. The AD5220 is used to convert the external analog signals into digital signals, the FPGA is used to collect high-speed data, the data collected by FPGA is processed by ARM, Embedded Linux, through the operation of the operating system to achieve real-time control of the FPGA. This paper first introduces the overall architecture of the system, then introduces the components needed in the system, and finally focuses on the FPGA module driver initialization.
