摘要
实现了基于FPGA硬件及VHDL语言设计的LED点阵汉字滚动显示,可通过按键选择,控制其滚动方式:左移或者右移及上移或者下移等。阐述了LED点阵显示汉字的原理,给出了点阵汉字滚动显示控制器的原理图、部分VHDL源程序及时序仿真图并进行了详细的分析,提出了系统扩展成实现16×16点阵汉字滚动的改动思路。
The LED dot-matrix Chinese characters scrolling display was designed based on FPGA hardware and VHDL language, which can control its rolling way by the key selection（left shift, right shift, move up or move down）. The principle of LED dot-matrix display Chinese characters, the schematic diagram of dot-matrix Chinese characters scrolling display controller are proposed, the VHDL source code and timing simulation map are analyzed in a detail. The ideas of expanding the system to realize a 16×16 dot-matrix Chinese characters scrolling.
