四位密码锁

使用Verilog语言对128点 基8FFT的实现(Implementation of 128-point basis 8FFT)

说明：  这个是64bit矩阵乘法实现代码，语言是verilog。(This is the 64 bit matrix multiplication implementation code, and the language is Verilog.)

载波同步，costas环，基于Verilog的载波同步环(Carrier synchronization, costas ring, based on Verilog carrier synchronization ring )

关于FPGA的一些例程，包括CORDIC数字计算机的设计，RS(204,188)译码器的设计等。(Some routines on FPGA include the design of CORDIC digital computers, the design of RS (204188) decoders, etc.)

说明：  QPSK 调制 与 解调的源代码 可综合 出波形(QPSK modulation and demodulation of the source code)

Very suitable for the study using computer vision, Analysis of the signal time domain, frequency domain, cepstrum, cyclic spectrum, etc. The performance of the program has reached a high level.

vhdl语言，国外教材，数字信号处理算法(vhdl language, foreign materials, digital signal processing algorithms)

该程序用vhdl编写的vga显示的小游戏，到时屏幕上会显示一个小球，一根棒子，一面墙，棒子可以通过按键控制来移动。而小球在不停的运动，遇到墙会反弹。(Game written by the program with VHDL VGA display, the screen will display a small ball, a stick, a wall, stick to move through the key control. Ball in constant motion, encountered the wall will bounce.)

这个程序是用来划分时钟，实现9600个传输速率的。该代码是在10兆赫的时钟频率运行。它计算特定的传输速率所需的比特数；
