Research Of Data Acquisition System Based On FPGA

The data acquisition system is an indispensable and important component of the signal and information processing system, and also is the key link of the digital signal process. The paper mainly introduce a research of data acquisition based on FPGA, the paper suggested a scheme of designing the high speed data acquisition system which is composed of high speed and high resolution A/D converter, high performance FPGA,PCI bus interface. As the control center and transmission bridge, FPGA played a very important part in this system. Utilizing FPGA not only accomplished the whole digital circuit and also highly improved the adapt ability and flexibility of the system.The paper based on the memory of the data acquisition, mainly studies the analog-digital conversion,FPGA design and the PCI bus interface design. completed the circuit hardware design and software design. Through the system simulation verified the feasibility of the system.
