231卷积码的verilog实现，前面是详细的文档说明，有源程序，绝对原创！！！！(Verilog achieve 231 convolutional code, preceded by a detailed description of the document, the source, the absolute originality! ! ! !)

VHDL实现SPI功能源代码 -- The SPI bus is a 3 wire bus that in effect links a serial shift -- register between the "master" and the "slave". Typically both the -- master and slave have an 8 bit shift register so the combined -- register is 16 bits. When an SPI transfer takes place, the master and -- slave shift their shift registers 8 bits and thus exchange their 8 -- bit register values.-SPI realize the functional VHDL source code The SPI bus is a 3 wire bus that in effect links a serial shift register between the

在八位七段数码显示管上显示8位学号，要显示的学号可以在程序内改，经设备验证无错误，且运行良好。

按键控制LED流水灯；按键1按下前8个灯从左到右依次点亮，按键2按下中间前8个灯从左到右依次点亮，按键3按下所有灯全亮(Water control button LED lights sequentially lit buttons the eight lights left to right 1 Press button 2 press from left to right is lit in the middle eight lights, key 3 Press All full bright light)

书名：LDPC原理与应用。是国内第一本介绍用LDPC编、译码基本原理及应用技术的一本书。对用 vhdl 或verilog实现硬件编程LDPC的人开发无线通信是很好的资料(Title: LDPC Principles and Applications. Is the first book describes using LDPC Encoding and Decoding the basic principles and application of technology, a book. Right to use vhdl or verilog hardware programming LDPC people to achieve development of wireless communications is a very good information)

异步的fifo,写时钟和读时钟相互独立，能够对数据进行缓存处理。希望对大家有用(Asynchronous fifo, write clock and the read clock independent of each other, capable of processing the data cache. I hope useful)
