说明：  verilog实现的FFT变换，经硬件测试其功能与Altera的FFT IP核相近(verilog implementation FFT transform, through hardware, test its functionality with Altera' s FFT IP core similar to)

说明：  VHDL实现的算术逻辑计算单元（ALU），包括modersim测试文件，即仿真结果。(VHDL implementation of the arithmetic logic calculation unit (ALU), including modersim test file, the simulation results.)

最近组长给分配的任务，这几天一直在做，比较郁闷的是用的器件是XC400XL系列的，只有ISE4.1支持，用惯了7.1i的我还是要适应一阵子（关键4.1是一个试用版的）。挺折腾的，不说了，放上顶层模块：-。。。

模拟SDH帧结构，设计了状态机，能从连续传输的SDH字节流中找出帧头；从SDH字节流中，提取E2字节，并按照64K速率分别串行输出E2码流及时钟；设计了输入信号，输出包括E2串行数据、E2串行时钟和SDH帧头位置指示

VC++6.0软件生成Altera公司FPGA内部存储器ROM初始化数据mif格式文件。方便通过QuartusII导入波形等参数。强调这个是例子，生成的是一个定点的正弦数据表文件，需要用到的请自行修改源代码。(This software generates internal memory ROM initialization mif format data file for FPGA product by Altera. Facilitate the passage of the waveform parameters such as import QuartusII)

与单片机相比，用CPLD/FPGA器件更适合于直接对高速AD采样控制。本实验接口器件为ADC0809，根据ADC0809的工作时序使用CPLD产生该控制信号，CPLD启动AD转换后，得到的数据送至单片机并在PC机及数码管上显示AD转换结果。(Compared with the microcontroller, CPLD/FPGA devices more suitable for direct sampling control of high-speed AD. The interface of the experimental device for the ADC0809 ADC0809 Timing CPLD is used to generate the control signal, the CPLD to start the AD conversion, the data sent to the microcontroller and the AD conversion result on the PC and digital tube display)

说明：  本书纸版由机械工业出版社于2014年出版，张强编著，电子版由华章分社（北京华章图文信息有限公司）全球范围内制作与发行(The book was published in paperback by China machine press in 2014, and edited by zhang qiang. The electronic version was produced and distributed worldwide by huazhang branch (Beijing huazhang graphic information co., LTD.))

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
