基于FPGA数据采集系统的研究

Data Acquisition System Research Based FPGA

针对数据采集卡成本高并且易受机箱内环境影响的这一不足,构建了以FPGA为核心的数据采集系统。系统使用FPGA作为核心CPU,控制各个模块,完成信号AD转换、FIFO缓存、USB串行通信等功能。该系统在VC++环境下编写动态链接库资源,以调用动态链接库的形式,实现USB与PC机的通信。

The paper aimed at shortcoming of data acquisition card which it is high cost and easily be affected within PC environment.Thus the system put up data acquisition based field programmable gate array （FPGA）,The modules in this system are controlled by FPGA as the CPU core to complete the functions such as signal sampling by ADC,data caching by FIFO, and communicating by USB,Then use Visual C＋＋ to program dynamic link library,which realized communication between USB and computer by quoting DLL.
