ofdm的verilog程序 利用ＦＰＧＡ实现

Xilinx FPGA中FFT IP核的使用笔记，内部有FFT硬核的端口说明和具体设置以及源代码，对于数字信号处理研究人员，能图像处理、雷达成像、实时通信开发人员较多的开发时间！(Xilinx FPGA in the FFT IP core using a laptop internal hard core of the FFT port description and specific settings as well as the source code for digital signal processing, image processing, radar imaging, real-time communications developers more development time!)

本代码可以用于产生正余弦信号波形，利用FPGA内部的ROM放置一个正余弦采样点的数据表格，通过循环取址的方法，实现波形连续输出。-This code can be used to generate positive cosine signal waveforms, using FPGA" s internal ROM to place a sampling point is the cosine of the data tables, the circulation method of taking the site to achieve a continuous output waveform.

从MIC输入一段音频然后，再从AOUT的接口播放出来的verilog 的代码-Input from the MIC for some audio and then AOUT interface from broadcast in the Verilog code

可以给VHDL初学者看的实例，全部经过验证(VHDL beginners can see examples of all the proven)

程序是完整的一个数字下变频器的一个Verilog程序，经测试可以使用，欢迎下载(Program is a complete Verilog program a digital down converter, tested can be used, please download)

---实现的部分VHDL 程序如下。 　　--- elsif clk1x event and clk1x = 1 then ---if std_logic_vector(length_no) >= “0001” and std_logic_vector(length_no) <= “1001” then -----数据帧数据由接收串行数据端移位入接收移位寄存器---rsr(0) <= rxda --- rsr(7 downto 1) <= rsr(6 downto 0) --- parity <= parity xor rsr(7) --- elsif std_logic_vector(length_no) = “1010” then --- rbr <= rsr --接收移位寄存器数据进入接收缓冲器--- ...... --- end if(--- achieve some VHDL procedure is as follows.--- Elsif clk1x event and then a clk1x = s--- if td_logic_vector (length_no))

此为华远显示320*240LCD驱动程序，该程序也适用于带RA8806控制器的LCD(This is the Huayuan display 320* 240LCD driver, the program also applies with RA8806 LCD controller)
