曼彻斯特编码技术用电压的变化表示0和1。规定在每个码元中间发生跳变。高→ 低的跳变表示0，低→ 高的跳变表示为1。每个码元中间都要发生跳变，接收端可将此变化提取...

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.)

利用VHDL 硬件描述语言设计一个0~9999 的加法计数器。根据一定频率的触发 时钟，计数器进行加计数，并利用数码管进行显示，当计数到9999 时，从0 开始重新计数(Use of VHDL hardware description language design a 0 ~ 9999 addition counter. According to a certain frequency of the trigger The clock, counter add count, and use digital pipes to show that when the count to 9999, starting from 0 to count )
