一篇比较好的spi接口的vhdl实现的参考

用PrimeTime的技巧，解决复杂时钟问题。(The world of telecommunications chips is full of messy clocking situations. This paper will cover the tricks and tehniques that author Paul Zimmer has developed to avoid the need to pour over reams of timing reports looking for problems. Best paper winner at SNUG San Jose 2001!)

vhdl寄存/计数器设计-VHDL Storage/counter design

用VHDL语言写的，音乐演奏程序，范例歌曲为“青花瓷”片段。-Using VHDL language, and music performance procedures, examples of songs as

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)

8051内核的hdl代码，实际上是verilog格式不过上载页面只有一个vhdl选择，值得一读， 里面对仿真和验证的说明很有含金量-the hdl code of 8051 core

说明：  一种用verilog语言实现的霍夫曼压缩编码算法(Huffman compression implemented by Verilog)

verilog实现的1024位的大数模逆算法，引入RAM作为数据通道-verilog to achieve the 1024 Modular inverse algorithms, the introduction of RAM as a data channel

把指定的噪声叠加到信号上去.有标准噪声库NOISEX-92，其中带有白噪声、办公室噪声、工厂噪声、汽车噪声、坦克噪声等等，在信号处理中往往需要把库中的噪声叠加到信号中去，而噪声的采样频率与纯信号的采样频率往往不一致，需要采样频率的校准。 (The specified noise superimposed to the signal up. Standard noise library NOISEX-92, with white noise, office noise, factory noise, car noise, tank noise in the signal processing often requires noise to be superimposed in the library The signal to noise of the sampling frequency and pure signal sampling frequency is often inconsistent sampling frequency of calibration.)

采用xilinx三太以太网ip核，tri-mode MAC完成千兆以太网数据传输(Too Ethernet using xilinx ip three nuclear, tri-mode MAC Gigabit Ethernet data transmission is completed)

verilog产生高斯白噪声，gwn_en信号产生使能，gdata是幅度服从高斯分布，功率谱密度为定值的高斯白噪声序列，共10位（现实中只能够做到带限，跟dac输出带宽有关，我的系统只能做到300kHz）(verilog Gaussian white noise, gwn_en signal enabled, gdata amplitude Gaussian distribution, power spectral density of white Gaussian noise sequence value, a total of 10 (in reality can only be band-limited, with dac output bandwidth related, My system can do 300kHz))
