基于FPGA数据采集系统的设计

Based on FPGA Data Acquisition Systems Design

现代电子设计技术的核心已日趋转向基于计算机的电子设计自动化技术,即EDA(Electronic Design Automation)技术,以硬件描述语言HDL(Hardware Description Language)为系统逻辑描述手段完成设计。本设计的功能是通过VHDL语言描述和MAX+plusⅡ软件相结合来实现对ADC00809的8路通道的数值进行循环检测报警;当需要对数据进行处理时,实现对采样信号的放大到2倍、缩小到1/2和保持采样信号不变这3种基本功能。

The Core of modern electronic design has become tend to electronic design automation technology,which be based on com-puter,with the method of HDL(Hardware Description Language) to describe the logic means to complete the system design.The function of this design is through the combination that VHDL language description and the software of MAX+plusⅡ to achieve cycle detection alarm to the 8-way channel of the ADC00809 for the numerical;when the need for data processing,and finishing sampling of the signal amplification to 2 times,Reduced to 1/2 and maintain the same signal sampling these three kinds of basic functions.
