FPGA 累加器

音频编码（ADPCM位） ；

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.)

FPGA，用VHDL语言产生可调的PWM波(FPGA, VHDL language adjustable PWM wave)

说明：  华为FPGA设计全套资料，学习FPGA的朋友可以下载看看。(Huawei FPGA design a full set of materials, friends learning FPGA can download and see.)

说明：  verilog实现awgn信道噪声的代码，支持可变的信噪比。利用移位寄存器来实现伪随机序列。(verilog code for implementation of awgn channel noise. support variable snr. use LSFR to implement the pseudo random sequence. )
