AD9747的SPI接口及寄存器配置

说明：  RISC-V 芯片设计规范,很有参考价值，开源芯片设计必备参考资料，希望对大家有帮助。(The RISC-V Foundation is chartered to standardize and promote the open RISC-V instruction set architecture)

说明：  基于FPGA的Veilog HDL实现代码，简单明了，希望能帮助verilog的初学者……(ＤＤＳ　based on Verilog ＤＨＬ for FPGA　)

直接序列扩频系统的收发系统，可以进行参数配置(this is a Verilog program )

说明：  基于K7的FPGA的DDR3读写程序，通过串口发送1024位的数据，写到FPGA的DDR3端，然后将数据从DDR3中读取出来，通过串口发送到PC端。(The DDR3 reading and writing program of FPGA based on K7 sends 1024 bit data to DDR3 end of FPGA through serial port, then reads data from DDR3 and sends it to PC through serial port.)

This is a simple verilog code for stopwatch undre xlinx ISE webpack based for NEXYS3 board.

基于FPGA Verilog驱动线性TCD1254GFG传感器驱动程序，驱动频率2MHz，帧率333帧每秒，曝光时间调节范围0-3000us，带数据读取时序1MHz。(The driver of linear TCD1254GFG sensor is driven by Verilog based on FPGA. The driving frequency is 2MHz, the frame rate is 333 frames per second, the exposure time adjusting range is 0-3000us, and the reading time sequence is 1MHz.)

本实验将TW2867第一通道输出解复用以后进行BT.656格式的解析，然后将奇偶场合并为一帧存入DDR2，读取的时候使用双线 性插值算法，将原始的720 x576的分辨率放大到800x600，然后在HDMI口输出。

VC++6.0软件生成Altera公司FPGA内部存储器ROM初始化数据mif格式文件。方便通过QuartusII导入波形等参数。强调这个是例子，生成的是一个定点的正弦数据表文件，需要用到的请自行修改源代码。(This software generates internal memory ROM initialization mif format data file for FPGA product by Altera. Facilitate the passage of the waveform parameters such as import QuartusII)

这是FIR滤波器实现参数化的数据位宽，cofficients和数据的定点宽度和阶滤波器。

韩福柱老师FPGA实验源码，用vhdl语言在xilinx FPGA上实现，包括ad采集，温度传感器读取，秒表，跑马灯和按键次数统计4个实验(Han Fu teacher FPGA column experiment source code, vhdl languages on xilinx FPGA implementations, including ad acquisition, temperature sensor readings, stopwatch, marquees and keystrokes 4 experimental statistics)
