基于VGA显示的10路逻辑分析仪

基于FPGA实现蜂鸣器播放音乐的功能 使用芯片为EP2C8Q208C8N,使用普通蜂鸣器，由于频率不同可实现放歌功能，本例设计的是《友谊地久天长》，使用Verilog语言编程，本例子有工程文件、仿真、波形，经过测试可以使用。(Play music based on FPGA buzzer functions using chip EP2C8Q208C8N, using ordinary buzzer, since the frequency of different functions can be realized sing, in this case the design is " Auld Lang Syne" , using Verilog language programming, this project examples files, simulation, waveform, tested can be used.)

VHDL实现快速傅里叶变换，内附带资料以及源代码。(VHDL fast Fourier transform, within the supplied data and source code.)

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)

这是一个16位乘法器Verilog程序，包括有符号位和无符号位乘法器(This is a 16-bit multiplier Verilog program, including the sign bit and no sign bit multiplier)

FPGA与DSP的EMIF通信，EMIF的RAM这方面相应的程序(FPGA and DSP EMIF communication)

nseval - Object evaluation, includes control method execution.

资源描述数字应用的移动值可用于FPGA

说明：  verilog实现awgn信道噪声的代码，支持可变的信噪比。利用移位寄存器来实现伪随机序列。(verilog code for implementation of awgn channel noise. support variable snr. use LSFR to implement the pseudo random sequence. )
