bits FIFO with synchronizer. Pass the sy nthesis using Synopsys tools

真是基于matlab的QPSK，格雷码，瑞利衰减信道，加性高斯白噪声仿真(Really based on matlab QPSK, Gray code, Rayleigh fading channel additive white Gaussian noise simulation)

提供了《自己动手写CPU》本书每一章涉及的OpenMIPS源代码、测试程序。(It provides the OpenMIPS source code and test program in each chapter, which is written in the book "do it yourself CPU".)

这是一个在Quartus II软件中编写的vhdl程序。程序下载后可用蜂鸣器播放音乐 -This is a Quartus II software in the preparation of the VHDL program. After the buzzer can be used to download music player

PLL是数字锁相环设计源程序, 其中, Fi是输入频率(接收数据), 数字锁相技术在通信领域应用非常广泛，本例用VHDL描述了一个锁相环作为参考，源码已经调试过。编译器synplicty.Fo(Q5)是本地输出频率. 目的是从输入数据中提取时钟信号(Q5), 其频率与数据速率一致, 时钟上升沿锁定在数据的上升和下降沿上；顶层文件是PLL.GDF-digital phase-locked loop PLL design source, in which Fi is the input frequency (receive data), the digital technology in the field of communications is widely used, the cases described in VHDL as a PLL reference source has been tuned. Compiler synplicty.Fo (Q5) is the local output frequency. Objective is to extract data input clock signal (Q5), its frequency and data rate line, the clock rising edge of the data locked up and the descending; Top-level document is PLL.GDF

数字时钟，包括流程图以及编码和完整的实验报告，内容详细丰富。(Digital clock, including flowcharts, and coding and a full lab report, detailed and rich.)

基于CPLD的签到器的设计，用三维数组队人名进行储存-Based on the attendance CPLD design, a few team names with three-dimensional storage

一份带有FIFO缓存的UART源码，采用verilog编写，实现批量数据的传输，数据缓存量可以通过修改源码中的FIFO的深度来改变。(This is a UART with FIFO. The UART is programmed using verilog, it can transmit or receive batch data. The amount of data buffered can be changed by changing the depth of FIFO.)

BISS-B 源代码。包含传感器模式和寄存器模式(BISS-B source code. Includes sensor mode and register mode)

DDS的频率转换可以以近似认为是即时的，这是因为它的相位序列在时间上是离散的，在频率控制字改变之后，要经过一个时钟周期之后才能按照新的相位增量增加，所以也可以说它的频率转换时间就是频率控制字的传输时间，-DDS frequency conversion can be considered similar to real-time, this is because it is the phase sequence in time is discrete, in the frequency control word change after one clock cycle to go through before a new phase in accordance with the incremental increase, so it can be said of the frequency switching time is the frequency control word transmission time,

我用VHDL写的正弦，用FPGA内部ROM，有仿真testbench,在quartus里可以运行。在板子里已经验证-I used to write VHDL sinusoidal, using FPGA internal ROM, has simulation testbench, you can run in Quartus. Yard has already been verified in the plates
