基于FPGA和ARM的线阵CCD信号采集器的设计

摘要

The design of linear CCD signal acquiring device based on FPGA and ARM was presented in this paper.The hard-ware circuit of linear CCD signal acquiring device was designed by using XC3S500E ( FPGA) chip and S3C2440 ( ARM) chip. The software codes of the signal acquiring device were written by using Verilog HDL and C language.The linear CCD signal acqui-ring system was built and experiments were carried one.The result shows that the signal acquiring device is able to accomplish CCD signal acquisition,storage,processing and transmission to the computer by Ethernet with the advantages of high quality sig-nals,high reliability,high transmission rate,good human-machine interface and convenient networking.The signal acquiring device has great value of application in the industrial production monitoring.%文中提出了一种基于FPGA和ARM的线阵CCD信号采集器的设计方案。选用XC3S500E（FPGA）芯片和S3C2440（ARM）芯片设计了线阵CCD信号采集器的硬件电路；采用Verilog HDL和C语言分别编写了信号采集器的软件。搭建了线阵CCD信号采集系统，并进行了实验。结果表明，该采集器能够实现线阵CCD信号的采集、存储、处理，以及通过以太网传输到上位机的功能，具有采集信号质量好、可靠性高、传输速率高、人机交互好、组网方便等优点，在工业生产监测中具有广泛的应用价值。
