毕业设计说明书(论文)中文摘要随着计算机技术的突飞猛进以及移动通讯技术在日常生活中的不断深入,数据采集不断地向高速、智能化的方向发展。本文针对此需求,实现了一种基于 FPGA 的高速数据采集系统。该系统利用 AD 器件对信号进行模数转换,利用 FPGA 设计内部模块进行 ADC 的逻辑控制并实现数据缓存功能。本文首先介绍了高速数据采集技术的国内外发展现状,确定了系统总体方案,完成了 FPGA 与 A/D 的芯片选型; 利用 Protel 完成了硬件电路原理图的设计, 并使用 Quartus II 完成了 FPGA 内部模块的设计,实现了时钟管理模块、数据采集控制模块和数据缓存模块。最后在 Red Cyclone 开发板上完成了 FPGA 程序的下载测试,验证了程序的正确性。关键词 FPGA 高速数据采集 A/D模数转换毕业设计说明书(论文)外文摘要 Title FPGA Based High-speed Data Acquisition Technology Abstract Along with the development puter technology byleaps and bounds and munications technology hasadvanced indaily life, data acquisition develops tohigh speed, intelligent continually. According tothe needs ,this paper designed ahigh-speed data acquisition system based onFPGA. The system used ADdevice torealize A/D conversion, used FPGA todesign internal module s ofADC logic control and realize dcircuit control data cache function. This paper first lyintroduce dthedevelopment ofhigh -speed data acquisition technology athome and abroad, determined the system overall program, complete d the FPGA and ADchip selection, finished the design ofthe hardware circuit principle byusing Protel, completed the design ofFPGA internal module by using Quartus II, realized clock management module, data acquisition control module and data cache module. Finally finished the FPGA program download test onthe Red Cyclone development board toverify the correctness ofthe program.
