基于FPGA的海量数据采集系统

FPGA-based Data Acquisition System for Massive

CF卡是目前应用最为广泛的存储介质。由于它的速度快,价格低廉以及容量大等诸多优点,在各种数据存储中被大力推荐和应用。在数据采集领域,基于FPGA的数据采集系统不但具有速度快,容易扩展等特点,而且由于没有MCU的干预,采集实时性高,使它能适合更广泛的应用场合。在数据采集与传输控制电路设计部分,给出了该模块的内部结构设计详图,传输控制采用FPGA作为主控元件,并且实现对数据的缓存,接着详细论述了FPGA内部各个功能电路的设计思路和具体实现过程。

In the field of data acquisition,FPGA-based data acquisition system not only has speed,features such as easy to expand,and because there is no MCU intervention,collecting real-time high,so that it can fit a wider range of applications.In data acquisition and transmission control circuit design of the modules give the details of the internal structural design, Transmission Control using FPGA as the main component,and the realization of the data cache,and then discusses in detail the various functions of the internal FPGA circuit design ideas and the specific implementation process.
