说明：  实现数字频率合成实验，加载数据ram,形成波形(The experiment of digital frequency synthesis is realized, and the data RAM is loaded to form the waveform)

本资源包括了加法器的VHDL代码实现，供大家学习。

一种实现计算机接口rs232与FPGA通信的基于VHDL语言设计的一段非常简洁的程序(A RS232 computer interface implementation with FPGA-based VHDL language communications designed a very simple procedure)

QPSK在赖斯信道下的模拟仿真，包括K=6和K=10下的情况(QPSK in, Laisi Xin Road, under the simulation, including the case of K = 6 and K = 10 under)

本例设计一个码率为500kb/s，字长为8 位、帧长为128 个字、帧同步码为EB90H 的PCM 采编器。用VHDL语言实现的。(This designs a code to lead for the 500 kbs|s, the word is long for 8, the growing is synchronous code of for 128 words and for the EB90 H of PCM adopt to weave a machine.Use what VHDL language carry out. )

说明：  在MATLAB下自编实现快速傅里叶分析，(Fast fft own procedures, faster than the system call fft slowe)

该模块已经成功运用在xilinx xc6slx45t，xc6slx75t多个产品中，经过实践证明，采用dna及其加密算法加密是一种成本低廉（无需另外加密芯片）可靠的加密手段。Xilinx Spartan-6 FPGA读取DNA数据并进行比较，产生比较结果信号输出。附带有xilinx DNA.ppt说明及调试注意事项。(The module has been successfully used in xilinx xc6slx45t, multiple xc6slx75t products, proven, and the encryption algorithm uses dna is a low-cost (no additional encryption chip) reliable means of encryption. Xilinx Spartan-6 FPGA reads the data and compare DNA to produce a comparison result signal output. Xilinx DNA.ppt comes with instructions and commissioning notes.)
