VGA的verilog实现

开发板的原理图 Aduio和 HDMI 是开发板自带的Demo。Schematic of Cyclone V and official demostration about HDMI and Audio.

vga interface with text rom. font size 80x40. core need core regeneration.

AES算法在FPGA上的实现，对AES算法所用的器件资源进行了总结(AES on FPGA the Fastest to the Smallest)

主要使用特权同学spatan6开发板实现的，适合学习设计超声检测系统的作为初步学习

说明：  实现在屏幕上显示绿色和红色相间的水平条纹。其中，vga_640x480模块将产生行同步信号hsyn和场同步信号 vsync; vga_stripes模块将产生red、green和blue三个输出。(The horizontal stripes of green and red are displayed on the screen. Among them, vga_640x480 module will produce line synchronization signal Hsyn and field synchronization signal vsync; vga_stripes module will produce red, green and blue three outputs.)

采用vhdl代码描述自适应滤波器，具有很好的可参考性，和实用性(Vhdl code to describe the use of adaptive filter, can be found with a good nature and usefulness of)

基于FPGA的SD卡音频播放器 经过调试可以直接用，音质很好有MP3的所有功能(FPGA-based audio player, SD card can be directly used after debugging, good sound quality with all the features of MP3)

说明：  verilog开发的经典教材，详细介绍了语法，常见历程，以及通用的程序段(verilog development of the classic materials, detailed information on syntax, common history, as well as the common program segment)

采用倍频及1/3、1/12倍频绘制的路面不平度频谱图（自编）(Using octave and 1/3, 1/12 octave drawn road roughness spectrum (self))

关于硬件描述语言Verilog的135个经典实例，从易到难，对Verilog的编程有很大的帮助。(About the Verilog hardware description language 135 classic example, from easy to difficult, for Verilog programming of great help.)
