基于FPGA的数据采集及显示

Data acquisition and display controller based on FPGA

在电力系统谐波分析中,模数转换(ADC)电路是影响系统检测性能的主要环节之一。基于NiosII的谐波分析系统具有逻辑控制能力强、信号处理实时性高、系统抗干扰能力强等特点。以Altera公司的DE2开发板为平台,实现了采样电路的硬件设计;在Quartus II中用Verilog HDL语言完成了与FPGA的接口设计,并最终实现VGA显示。

In analysis of power system harmonic, analog-to-digital converter （ADC） circuit is one of the main links which affects detection performance of system. NiosII-based harmonic analysis system has features of good logic control ability, high real-time of signal processing, strong anti-interference ability, etc. Hardware design of sampling circuit is realized with the platform of Altera＇s DE2 board. Quartus II used in the Verilog HDL language to complete the interface with the FPGA design, and eventually VGA display.
