本文件给出了基于VHDL语言的VGA图像显示程序及其工程问件。(This document is presented based on VHDL language VGA image display program and the project asked the pieces.)

VHDL语言设计；功能描述：键盘扫描，不包含去抖电路-VHDL language design Function description: the keyboard scanning, does not contain a circuit debounced

tdma参数化模块。可以自动生成2的n次的tdma哥时隙，用户可根据需要自己配置参数(tdma see the number of model lumps. 2 n basis following manner tdma chance possible 以自 dynamic generation, for root needed self-placement see number)

fpga实现ddr数据收发测试，完整的工程，下载解压后，即可正确运行，已多次验证无误(FPGA DDR data receive and receive test, complete engineering, download and unzip, can run correctly, has been verified many times)

使用Altera公司的FPGA进行VHDL开发。使用quartus2 9.0软件在EP1C3T144C8开发板上实现对4x4键盘的输入控制，并显示在一个8段式数码管上。(The use of Altera' s FPGA-VHDL development. Use quartus2 9.0 software EP1C3T144C8 the development board to realize 4x4 keyboard input control, and displayed in an eight-stage digital pipe.)
