串行至并行转换器

对SPI接口的verilog编程，SPI is a simple interface that allows one chip to communicate with one or more other chips.   

正弦信号发生器，用VHDL来完成，抗干扰能力较强，(Sinusoidal signal generator, using VHDL to accomplish, a strong anti-interference ability,)

this program is a simulation for Aloha

说明：  HDMI做为视频输出输入接口已经广泛使用很长时间，主要通过TMDS差分编码传输。本实验通过在HDMI屏幕上显示彩条和输入输出环通实验，来练习视频的时序和视频颜色的表示，为后面视频处理实验做个基础。(HDMI as video output input interface has been widely used for a long time, mainly through TMDS differential coding transmission. In this experiment, by displaying color bars and input/output loop experiments on HDMI screen, video timing sequence and video color representation are practiced to lay a foundation for video processing experiments later)

本程序是锁相环的仿真程序，具有接收端载波同步的功能。注释详尽，程序规范。发端的调制方式有单载波调制，BPSK调制，QPSK调制可供选择。程序中有星座图，锁相环的频差、相差图，以及解调后的基带波形。(This program is a phase-locked loop simulation program, the with carrier synchronization receiving end function. Notes detailed program specifications. The originator of the modulation scheme to choose a single carrier modulation, BPSK modulation, QPSK modulation. Program constellation diagram, the PLL frequency difference, a difference of FIG, and the demodulated baseband waveform.)

AES加密算法verilog源码 This project is the hardware implementation of the  Advanced Encryption Standard with a key size of 128 bits. The implementation adheres to the FIPS-197 document which explains the same.The core can do both encryption as well as decryption.The documents aes_arch.doc and aes_tb_readme.txt give further details of the rtl implementation and test bench respectively. This code was written originally with 128 bit ports for both input and key but later converted to 64 bits each to save on i/o pins. It can be reverted back easily if one just changes the port widths and dispenses with the load signal in the top module and making approriate changes in process where load is used.Synthesis results have been included for Xilinx Spartan-3 device.The directory structure of the project is as under- AES128

说明：  用matlab将图片转成灰度图TXT，再通过verilog将数据导入FPGA中，采用高斯滤波算法来处理，再将处理后的图片数据导出到TXT中。(The image is transformed into gray-scale image TXT by MATLAB, and then the data is imported into FPGA by Verilog, processed by Gauss filter algorithm, and then the processed image data is exported to TXT.)

在这个项目中古代VEDIC数学用于乘法运算。主要应用于数字信号处理器的乘数的加密算法。URTHVA TRIYAGBHYAM 佛经用来执行。UT 据说是纵向和横向的乘法。

在Quartus II 上编程的基于FPGA的LED显示实验(Programming in the Quartus II LED display experiment based on FPGA )

说明：  用于读取海德汉绝对位置编码器的位置数据。ENDAT2.1接口(Read the data from ENDAT2.1)
