摘要
随着信息技术的飞速发展,各种数据的采集和处理在现代工业控制和科学研究中已成为必不可少的部分。数据采集系统是计算机智能仪器与外界物理世界联系的桥梁,是获取信息的重要途径。以Xilinx公司的Spartan-3系列FPGA芯片XC3S400为核心,采用TI公司的TLC0820型号的A/D转换器作为模数转换器件,设计了一个基于FPGA的数据采集系统,并用Verilog HDL语言作为描述语言实现了对TLC0820的采样控制和FPGA的数据处理等过程的控制,以Xilinx ISE 9.1i软件为平台,进行了设计输入、分析与综合、仿真与验证等过程仿真实现了这一系统。
With the rapid development of information technology,a variety of data acquisition and processing in the modern industrial control and scientific research have become an indispensable part.The data acquisition system is a bridge between the computer smart instruments and the outside physical world,it is also an important way to get information.The FPGA chip XC3S400 of Xilinx company is as the core,which belongs to Spartan-3 family,and the ADC TLC0820 of TI company is as the analog to digital converter to design a data acquisition system based on FPGA.Using Verilog HDL language as description language implements sampling control of TLC0820 and data processing control of FPGA.By design input,analysis and synthesis,simulation and validation process simulate this system,which based on the Xilinx ISE 9.1i software.
