基于Verilog的32位CRC校验

一个简单的千兆以太网UDP协议的实现,可以实现数据的收发和ARP，实现PC端与FPGA的以太网通信(A simple implementation of Gigabit Ethernet UDP protocol can realize data sending and receiving and ARP, and realize Ethernet communication between PC and FPGA.)

很有用的10bit串并转换verilog程序，需要的可以拿去参考下，在quartusII上已验证过(Useful 10bit string and convert verilog program, need to take a reference, has been verified in quartusII)

采用xilinx的ROMIP核产生类似正弦信号，经过FFt后可以观察结果(Using the xilinx ROMIP nuclear generating similar sinusoidal signal can be observed through the results after FFt)

这是用Verilog写的RS485通信程序，可以使用，希望大家能够互相交流，(This is a Verilog writing RS485 communication program, can be used, I hope we can communicate with each other,)

说明：  通过spi实现加速度计adxl357读取xyz三轴方向的加速度值(Accelerometers adxl357 read the acceleration value of XYZ three-axis direction through SPI)

说明：  RISC全部源码，包含仿真文件，使用makefile脚本编写，能通过vcs编译(RISC all source code, including simulation files, using makefile script, can be compiled through VCS)

基于FPGA的正弦脉宽调制波vhdl代码，同时输出正弦波与SPWM(Sine pulse width modulation wave VHDL code based on FPGA, at the same time with SPWM output sine wave)
