LabVIEW Aided Design Digital Filter and FPGA Implementation

针对辐照加速控制系统在FPGA平台联合LabView平台下数字滤波器的设计。该方法对来自超导腔的信号经过高速ADC采样的数据进行低通数字滤波,以降低外界干扰信号对进入FPGA的中频信号的影响,以提高辐照加速器的控制精度。LabView是一种基于图形编程语言(G语言)的开发环境,采用交互界面设计、模块化编程。辐照加速器控制系统中,该滤波器是重要组成部分。提供一种通过FPGA结合LabView平台的设计方法。

The design of the digital filter under the FPGA platform combined with the LabView platform is aimed at the irradiation accelerated control system.This method lowpass digital filtering to the data of high-speed ADC sampled from the superconducting cavity,so as to reduce the influence of the external interference signal on the FPGA IF signal,and improve the control accuracy of the irradiation accelerator.LabView is a development environment based on graphic programming language(G language),which adopts interactive interface design and modular programming.The filter is an important part of the radiation accelerator control system.This article provides a design method that combines the FPGA with the LabView platform.
