这是用VHDL编写的CRC32

这是个UART发送的VHDL程序，调试过，还可以-This is a UART to send the VHDL program, debug, and can also be

说明：  ad9649的fpga驱动程序,FMC接口，基于Xilinx KC705(AD9649 Evaluation Board, FMC Interposer & Xilinx KC705 Reference Design)

ADI JESD204接口的ADC与Xilinx FPGA接口IP，包含Verilog和VHDL源代码，AXI总线接口，ADC串行控制接口(ADI IP for interfacing JESD204 ADC to Xilinx FPGA, include Verilog/VHDL source code, AXI interface and serial config interface )

说明：  FPGA应用状态机版，适合初学者学习状态机三段式，ASMD图的理解和翻译，以及Verilog语言的应用 最后对仿真的一些理解 其中包含HDL设计及testbench描述 根据要求设计了一个能求出一个32bit字中两个相邻0之间最大间隙的电路。(FPGA application state machine version, suitable for beginners to learn state machine three-stage, ASMD chart understanding and translation, and Verilog language application. Finally, some understanding of simulation, including HDL design and testbench description According to the requirements, a circuit is designed to find the maximum gap between two adjacent zeros in a 32 bit word.)

cordic 算法知道正弦和余弦值，求反正切，即角度。(The CORDIC algorithm knows sine and cosine values and asks for inverse tangent, that is, angle.)

说明：  串口操作源代码，本代码采用veilog hdl语言编写，并经过本人多次验证。(source code, the code used veilog HDL language, and after I repeatedly verified.)

片上网络NOC基于fpga实现的，routing模块。(NOC-chip networks realized fpga-based, routing module.)

用于ATmega128的一些通讯程序，包含I2C　UART，SPI等接口，用ICCAVR编译(for ATmega128 some communications procedures, including UART I2C, SPI interfaces with ICCAVR compiler)

本程序调试了TI的高精度模数转换芯片ADS1115,此模数转换器采用双积分型，16位，为IIC通信方式，调试较复杂，在对直流采集方面有着广泛的应用(This program debugging TI s high-precision analog-digital conversion chip ADS1115)

Xilinx CPLD源代码，使用XC9500系列CPLD,驱动液晶-Xilinx CPLD source code, use the XC9500 series CPLD, LCD Driver
