七分频数字电路—VHDL

verilog 代码. 经验证成功,可以作为标准单元库,为FPGA设计者使用.-Verilog code. Certified success, as a standard cell library for the use of FPGA designers.

8b10b编解码，用于光通信和千兆以太网，verilog编写，已验证(8b10b codec for optical communications and Gigabit Ethernet, verilog prepared Verified)

用VHDL制作的I2C控制器，是一个component,之间添加就可以使用。-VHDL produced using I2C controller, is a component, you can use to add between.

FPGA SDI 输入，HDMI输出例程(FPGA SDI_IN,HDMI_OUT)

vhdl编写的FPGA与DSP接口程序，在FPGA内分配了两块双BUFFER与DSP进行通信(vhdl prepared FPGA and DSP interface program, the FPGA within the allocated 2 pairs of BUFFER to communicate with the DSP)

K2FPGA开发板实验教程——I2C协议说明及verilog实现读写I2C器件，中文内涵代码，验证可用。(K2FPGA development board test tutorial- I2C protocol description and verilog read and write I2C devices, Chinese connotation code to verify availability.)

vhdl波形发生程序.实现4种常见波形正弦、三角、锯齿、方波（A、B）的频率、幅度可控输出（方波 A的占空比也是可控的），可以存储任意波形特征数据并能重现该波形，还可完成 各种波形的线形叠加输出。 -vhdl waveform occurred procedures. 4 achieve common sinusoidal waveform, 1.30, sawtooth, square-wave (A, B) the frequency and amplitude control output (square A duty cycle is also controllable), can store data of arbitrary waveform characteristics and able to reproduce the waveform, but also through a variety of linear superposition of the waveform output.

说明：  DA芯片输出控制 SPI协议 只写不读 FPGA用 verilog(DA-chip SPI protocol output control does not read write-only FPGA with verilog)

运用quartus 软件模拟的电子琴，实现按键出现不同音调的音乐。(Quartus software simulation using keyboard, keys appear to achieve different tones of music.)

FPGA设计软件的绝佳入门书籍，本人珍藏，全部吐血奉献之2，请大家赶紧下！-FPGA design software, an excellent entry-books, I treasure all the blood sacrifice of 2, please hurry under the U.S.!
