FPGA MAC控制器

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.)

此代码为使用SPI 用于实现28335控制AD9959输出信号的频率、幅度(This code uses SPI The Frequency and Amplitude of AD9959 Output Signal Controlled by 28335)

可以实现2PSK的信号调制，已经过Modelsim波形仿真(It can realize 2PSK signal modulation and has been simulated by Modelsim waveform.)

在zedboard开发板上采用vivado通过AXI进行DMA数据传输(Using vivado to transfer DMA data through AXI on zedboard development board)

数字频率计，测量范围0-1GHZ,测周测频自动转换，精度极高，花了很长时间，不过还是有一点点小问题，有待改进.(Digital frequency meter, range 0-1GHZ, automatic conversion measured weekly frequency measurement, high precision, took a long time, but still a little small problems to be improved.)

说明：  APPCM算法和AD/DA芯片驱动在CPLD中的实现，已在实际硬件中测试OK，quartus2环境(APPCM algorithm and AD/DA chip in the drive to achieve in the CPLD has been tested in actual hardware OK, quartus2 environment)

一个Verilog的JTAG程序例子，包括完整的说明文档和源文件。(tap_top.v This file is part of the JTAG Test Access Port (TAP) http://www.opencores.org/projects/jtag/ Author(s): Igor Mohor (igorm@opencores.org))

这是实现一个关于dmbt 3780点的fft 的算法的verilog code，该代码已经完成了硬件验证，为了捞点分，我把箱底的东东拿出来给大家分享了，希望对正在做这方面的同志提供一点帮助，唉

简易信号波形发生器，可以产生四种波形，频率1k-20K步进可调。学习Verilog HDL的好例子。(imple signal waveform generator, can produce four waveform, frequency 1 k-20 k step can be adjusted. Learning Verilog good example of HDL. )

说明：  一本很经典的IC设计中文入门书籍，由任艳颖，王彬编著，翻印几百万册(A very classic introduction to Chinese in IC design book, compiled by Ren Yanying and Wang Bin, reprinted millions of copies)
