VHDL手册很不错，适合硬件描述语言指南

简单电子玩具的感知模块程序设计,通过外部输入信号改变内部信号.从而改变玩具的状态-simple electronic toys perception module programming, through external input signal a change in the internal signal. In order to change the state of toys

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)

FIFO的Verilog程序 已在modelsim中编译通过 并且可以通过DC进行综合-FIFO procedures have been in the Verilog in ModelSim compiler and can be passed through the integrated DC

本设计是基于EP4CE15F17C8N和12864液晶的频率计程序(The design is based EP4CE15F17C8N and 12864 LCD frequency meter program)
