FPGA的核心源代码，有利于学习，适合初学者…

这个是讲pll的具体用法的,一般在fpga设计中都会用到 他,这个是lattice的xp2的pll的介绍,不过,fpga 都是相通的其他两家也差不多(Pll say this is the specific usage, the general design in the FPGA will use him, this is the lattice of the pll of xp2 introduction, however, fpga are connected to other two similar)

基于DE2-70开发板的VGA接口实现程序，可在VGA屏幕上显示800*600分辨率的图像，刷新频率60Hz

D触发器的基本功能的理解及应用，特别是记忆传输功能使用WAIT语句编写地理解-D flip-flop understanding of the basic functions and applications, in particular the memory transfer function using the WAIT statement is prepared to understand

说明：  学习VHDL可以用得上，有很多实例，可以对照着自己写一些东西(VHDL can be useful to learn, there are many examples, can be done to write something)

说明：  一个解决除法溢出的例子，可以学习到很多，注释很详细(A solution to the division overflow example, you can learn a lot, very detailed notes)

UART_DMA的方法是使用nios实现UART方式实现DMA传输，在硬件平台上通过验证实现(UART_DMA way is to use uart dma transfer nios implemented in the hardware platform validated by)

千兆以太网设计，包括组包解包，可以实现大数据传输功能。(Unpack the gigabit Ethernet is designed, including group package, can realize large data transfer function.)

电子密码锁，采用基于fpga的设计，可以设置6位密码-Electronic code locks, FPGA-based design, can be set 6 password

CAN VHDL Code. Behavioral implementation of CAN bus interface.

In communication systems channel poses an important role. channels can convolve many different kind of distortions to our information. In perticular wireless channels multipath distortion is sevear. and more sevear is such distortion is random. To handle this, multipath affected channels require Equalizers at receaver end. such equalizer uses different learning Algorithms for identifying channels continuously. This project is VHDL implementation of LMS learning algorithm with pipelined architecture. so this implementation can work with higher data rates with less clock speed requirments and so with less power consumpiton It uses Fixed point arithmatic blocks for filtering so suitable for coustom asic.
