IIC EDID码配置

lattice的官方8b10b代码, 1012年版本，diamond3.5编译。(lattice 8b10b encoder decoder code)

vhdl N-0.5分频方法设计，可以输入任意数值N，即分得到N－0.5的频率。-vhdl N- 0.5-frequency method, we can input arbitrary numerical N, namely, to be N- 0.5 frequencies.

SPI读写AD9361，通过串口回读关键寄存器读写是否正确。(SPI reads and writes AD9361, reads and writes the key registers correctly through the serial port.)

NIOS II IDE 编程， uart_txd测试程序，仅供参考。-NIOS II IDE programming, uart_txd testing procedures, for information purposes only.

altera 公司的15IP源码 亲自测试还不错 有DIV, CONTER-ALTERA the 15IP source personally tests are also good DIV, CONTER

说明：  ad9361 matlab驱动代码，运行此代码可在matlab中控制AD9361(AD9361 matlab driver code, running this code can control AD9361 in MATLAB)

FPGA实现FFT算法的源代码及工程文件，此工程为ISE工程项目。有详细的说明，可以运行。(FPGA Implementation of FFT algorithm source code and project files, this works for the ISE project. There are detailed instructions, you can run.)

说明：  Digital pre-distortion (DPD) is an advanced digital signal-processing technique that mitigates the effects of power amplifier (PA) nonlinearity in wireless transmitters. DPD plays a key role in providing efficient radio digital front-end (DFE) solutions for 3G/4G basestations and beyond. Modern FPGAs are a promising target platform for the implementation of flexible wireless DFE solutions, including DPD.

这份代码完成的功能是通过蜂鸣器播放《梁祝》这首曲子，当然可以自行更改代码，以播放其它的乐曲，所用的硬件描述语言是VHDL，代码有四部分构成，顶层模块、预分频模块（产生基频）、音乐表格和分频模块（产生所需的各音调）。
