畢業(yè)設(shè)計(jì)論文 基于MCU和FPGA的數(shù)字式相位測量儀的設(shè)計(jì)


 
摘  要

該設(shè)計(jì)采用單片機(jī)與FPGA相結(jié)合的電路實(shí)現(xiàn)方案，很好地發(fā)揮了FPGA運(yùn)算速度快、資源豐富、編程方便的特點(diǎn)，并利用了單片機(jī)較強(qiáng)的運(yùn)算、控制功能，使得整個(gè)系統(tǒng)模塊化、硬件電路簡單、使用操作方便。文章主要介紹設(shè)計(jì)方案的論證、系統(tǒng)硬件和軟件的設(shè)計(jì)，給出了詳細(xì)的系統(tǒng)硬件電路圖和系統(tǒng)軟件的設(shè)計(jì)過程。實(shí)踐表明，該相位測量儀具有較好的性能。

Abstract
 
    The combination of MCU and FPGA is adopted in the design.  The system exerts FPGA’、characteristics of high operating speed,
rich resource and convenient programming.  The powerful operation and control I'uncLions oI' MCU are adopted, Lhus Lhe system is modularized,
Lhe hardware is simple and Lhe operation is easy.  The demonstration oI' Lhe design strategy, design oI' hardware and software are mainly intro-
duced in Lhe paper. The detailed hardware circuits and main program oI'system software are given. The practice shows LhaL Lhe phase measuring
instrument is good in performance and it has been successfully used in Lhe contest oI' electronic design I'or national students.

Keywords:  MCU； Design strategy；   Phase measuring instrument
