说明：  fPGA中的竞争冒险现象的来源及其解决方法(FPGA in the source of the phenomenon of competitive risk-taking and their solutions)

利用FPGA实现QPSK数字调制。编程采用Verilog HDL语言。(By using the FPGA realization of QPSK digital modulation. Use Verilog HDL language programming. )

一个解决除法溢出的例子，可以学习到很多，注释很详细(A solution to the division overflow example, you can learn a lot, very detailed notes)

ARM处理器的IP核，用verilog编写的，对处理器和相关的CPU架构知识有很大帮助。(ARM processor IP core, written in verilog processor and CPU architecture knowledge.)

数字频率计 数字频率计-Digital frequency meter digital frequency meter

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)

this is verilog code for designing ALU in fpga.

一个具有“百分秒，秒，分”计时功能的数字跑表，可以实现一个小时以内的精确至百分之一秒的计时。 数字跑表的显示读者可以通过编写数码管显示程序来实现，本训练只给出数字跑表的实现过程。 读者还可以通过增加小时的计时功能，实现完整的跑表功能。(A " percentage of seconds, seconds, minutes," digital stopwatch timer can be achieved within an hour of precision to the hundredth of a second time. Digital stopwatch readers can display the digital display through the preparation of procedures to achieve, given the training is only the realization of the process of digital stopwatch. Readers can also function to increase hours of time to achieve full stopwatch function.)
