高速数据采集系统的设计与实现

Implementation of Data Acquisition System

由于雷达数据处理的要求,需要对雷达数据进行实时地存储记录。本文介绍了一种基于光纤通道的高速数据采集系统,以FPGA为平台,PCI Express为接口,链式DMA为传输模式,实现了最高速率为6Gbps的数据采集系统。

For the purpose of processing the radar data, the storage of a large number of data are needed. The paper introduces the design of data acquisition system based on fiber. This system uses FPGA as flat, uses PCI Express as interface, and uses chaining DMA as transmission pattern. It can achieve the data acquisition with 6Gbps.
