一个完整的基于FPGA的IIR低通滤波器的设计方案，是一个研究生论文(master and doctor dissertation)

本代码为简单AXI接口控制模块，具备数据的读写等传输功能，对总线传输学习者来说是很好的学习资料，可在此代码基础上进行更复杂功能接口的模块的开发。

我从一本书上抄来的 但用MAX+PLUSII编译有些问题 初学者 见谅-from a book copied but with the MAX PLUSII compile some of the problems beginners forgiven

包含UART口的VERILOG源程序，该程序在FPGA上验证通过，可作为芯片设计，或FPGA设计的一个完整IP核，硬件设计的兄弟们可参考一下。-include UART port of VERILOG source, the program tested in FPGA, as chip design, or FPGA design of a complete IP cores, hardware design brothers can make reference.

huawei代码编码规范，包含基本的verilog的语法等编码规范，业界经典(Huawei code coding specification, including the basic syntax of the Verilog code, the industry classic)

自己做的一个关于more状态机的三种描述的比较。以后会有更多的资料，请大家关注。-doing more of a state machine on the three described earlier. Many more information, please everyone"s attention.

从github下载的，能够参考设计AXI4的协议接口(AXI4 Verilog template)

verilog jtag源码及原理，还有debug模块。边界扫描等(verilog jtag source and principle, as well as debug module. Boundary-Scan, etc.)

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)

语音采集,直接在QUARTUSII中打开调试.-err
