以上是VHDL硬件描述语言写的一个简单锝路流水灯程序,希望对刚接触VHDL的朋友有一定帮助...

实现简单自动售货机的基本功能。投币找零功能，并用Led数码管显示，输出结果用Led显示。(Basic functions simple vending machines. Coin change for function and use Led digital tube display, the output display Led.)

应用背景它的所有关于自动售货机项目，在两个编码，并显示出在DE2开发板关键技术= Quartus两，和DE2开发板，最好的贩卖机的客户，甚至机器，小吃的源代码，食品

C语言写得FIR滤波器代码，简单实用，是学习滤波器设计的好材料，附带PPT滤波器设计说明(C language written FIR filter code, simple and practical, is a good learning materials of filter design, with PPT filter design )

DDR SDRAM控制器verilog代码及中文说明文档,对DDR开发很有用的哈。-Verilog source code for DDR SDRAM controler design,including guide book in chinese.

The SPFD5408A, a 262144-color System-on-Chip (SoC) driver LSI designed for small and medium sizes of TFT LCD display, is capable of supporting up to 240xRGBx320 in resolution which can be achieved by the designated RAM for graphic data. The 720-channel source driver has true 6-bit resolution, which (The SPFD5408A, a 262144-color System-on-Chip (SoC) driver LSI designed for small and medium sizes of TFT LCD display, is capable of supporting up to 240xRGBx320 in resolution which can be achieved by the designated RAM for graphic data. The )

介绍分频器的好资料。不光有奇数分频、偶数分频，还有小数分频。相信把这个资料理解透了后以后分频器的设计就不是问题了。(Introduction divider good information. Not only have an odd frequency, even frequency, there are fractional. I believe understanding this information through the post after the Divider is not a problem.)

基于VHDL语言开发的I486总线接口程序。实现了一个三态的总线，可保证数据的正常传输。-based on VHDL development of the I486 bus interface procedures. Implementation of a three-state bus can ensure that the normal data transmission.

说明：  通过循环读写DDR3内存，了解其工作原理和DDR3控制器的写法，由于DDR3控制复杂，控制器的编写难度高，这里笔者介绍XILINX的MIG控制器情况下应用，是后续音频、视频等需要用到SDRAM实验的基础。(Through reading and writing DDR3 memory circularly, we can understand its working principle and the writing method of DDR3 controller. Because of the complexity of DDR3 control, it is difficult to write the controller. Here, the author introduces the application of Xilinx's MIG controller, which is the basis of SDRAM experiment for subsequent audio and video.)

应用背景此代码是用于执行器和传感器，可以在网络中实现一个很好的连接与其他节点和主。关键技术VHDL代码 ；可以控制位CRC校验和填料-掩模的验收规范
