【正文】 編號(hào) 淮安信息職業(yè)技術(shù)學(xué)院 畢業(yè)論文 題 目 基于 FPGA 的 LED 點(diǎn)陣設(shè)計(jì) 摘 要 I 摘 要 主要研究基于 VHDL 的 Led 點(diǎn)陣漢字滾動(dòng)顯示。首先描述了基于現(xiàn)場(chǎng)可編程門(mén)陣（ FPGA）的硬件電路，以及點(diǎn)陣顯示漢字的原理 。 然后在單個(gè) 16X16 LED 發(fā)光二極管點(diǎn)陣上滾動(dòng)漢字的原理；最后給出了描述其功能的 VHDL 語(yǔ)言程序設(shè)計(jì)方法。通過(guò)編程、調(diào)試、仿真、下載正確地實(shí)現(xiàn)了漢字滾動(dòng)顯示掃描 結(jié)果，其硬件系統(tǒng)的實(shí)驗(yàn)驗(yàn)證也獲得了與軟件模擬仿真結(jié)論相吻合的結(jié)果。 關(guān)鍵詞 ： LED 點(diǎn)陣； FPGA； VHDL 語(yǔ)言；漢字滾動(dòng)顯示 Abstract II Abstract Primary research is based on FPGA, Led Scrolling dot matrix characters. First described based on field programmable gate array (FPGA) hardware circuit, as well as the principle character dot matrix display。 and then in a single 16X16 LED scrolling LED dot matrix on the principles of Chinese characters。 Finally, the VHDL description language program of its functions design. Through programming, debugging, simulation, download the correct character scroll achieved scan results, the experimental verification of its hardware and software are also obtained findings consistent with simulation results. Keywords: LED dot marix。 FPGA。 VHDL language。 Chinese character scrolling display. 目 錄 III 目 錄 摘 要 .............................................................................................................................
