.页眉. .页脚. 基于 FPGA 的点阵汉字显示摘要: 本课程设计主要研究基于 FPGA 的点阵汉字动态显示。首先介绍了 LED 点阵显示汉字的原理,然后通过编程控制可以显示中英文字符、图形及视频动态图形。LED 显示以其组构方式灵活、亮度高、技术成熟、成本低廉等特点在证券、运动场馆及各种室内外显示场合得到广泛的应用。本实验结合实例运用基于 FPGA 的VHDL 语言编程使其循环显示“武汉理工大学信息工程学院庞锦”这几个字。论文描述了基于现场可编程门阵(FPGA )的硬件电路,以及点阵显示汉字的原理; 然后介绍在单个 16X16 LED 点阵上滚动汉字的原理;最后给出了描述其功能的 VHDL 语言程序设计方法。通过编程、调试、仿真、下载正确地实现了汉字滚动显示扫描结果,其硬件系统的实验验证也获得了与软件模拟仿真结论相吻合的结果。关键词: FPGA VHDL 语言点阵汉字显示 The dot matrix characters display based on FPGA Abstract: This course design is primary research based on VHDL of the dot-matrix characters displayed . Firstly intr oduces the principle of LED dot-matrix display characters, Then through the programming control can show Chinese and English characters, graphics and video dynamic graphics . LED display with its group structure flexible, high brightness, mature technology and low cost characteristics widely used in the securities, sports venues and a variety of indoor and outdoor show occasion. In this study, with examples using VHDL language programming of FPGA-based make the cyclic display "wu han university of science and technology information engineering college Pang Jin ” the words . The papers first described based on field programmable gate array (FPGA) hardware circuit, as well as the principle character dot matrix display; and then ina single 16X16 LED scrolling LED dot matrix on the principles of Chinese characters; Finally, the VHDL
