用verilog hdl 硬件描述语言写的一个范例程序，led的，扩展性极强，欢迎大家下载使用。-Verilog hdl using hardware description language to write an example of the procedure, led, and highly scalable, welcome to download.

I2C总线协议 Verilog源代码.试过，没有错误！可以直接使用(I2C bus protocol Verilog source code. Tried, no errors! Can be used directly)

本代码是用VERILOG语言描述的AMI码的解码的程序，经过调试是正确的。代码简单易懂。(This code is described in VERILOG language AMI code decoding process, after debugging is correct. Code is easy to understand.)

说明：  基于FPGA的1553b接口设计详细设计论文(1553B design based on FPGA)

说明：  使用STM32官方提供的DSP库进行FFT，虽然在使用上有些不灵活（因为它是基4的FFT，所以FFT的点数必须是4^n），但其执行效率确实非常高效，看图1所示的FFT运算效率测试数据便可见一斑。该数据来自STM32 DSP库使用文档(. Using the official DSP library provided by STM32 for FFT is not flexible in use (because it is the FFT of base 4, so the number of FFT points must be 4 ^ n), but its execution efficiency is really very efficient, as can be seen from the test data of FFT operation efficiency shown in Figure 1. This data comes from STM32 DSP library usage document)

vga显示代码,里面有ise工程文件,是直接调过去的,大家下载下来吧-vga display code, which has ise project file is transferred directly past, everyone download it

说明：  NCO生成原理接介绍、CORDIC算法原理介绍以及MATLAB与Verilog语言实现(Introduction to NCO generation principle)

跑马灯-是移位寄存器 有6个灯，无延时entity-Bomadeng-shift register is a six lights, without delay entity

此压缩包里面有基于vivado平台的工程，包括了正弦信号的产生，还有fir滤波器的设计以及fft算法的设计实现(in this package,there are three projects of the generation of the signal of sin and the design of fir filter and the ari)

fpga正弦波发生函数，可用于自动生成rom文件(fpga sine wave generating function)
