用vhdl实现24小时计数器，方法简单实用。 仿真环境MAXPLUS

数字跑表 该跑表具有启动、复位、暂停、暂停后继续计时等功能 能显示的秒计数时间精确到小数点后第二位，即能显示**.**s 按钮设置防抖-Digital stopwatch in the stopwatch with start, reset, suspend, suspended after the time and other functions can show the seconds counting time accurate to the second place after the decimal point, that can show**.** s Anti-Shake button settings

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)

基于CPLD的38译码器程序设计，使用VHDL语言编程，38译码器显示在数码管上。

CPU 5级流水线实现（加hazard处理与板级验证，板级验证带有按键消抖）(5-stage pipelined CPU (plus hazard dealing with board-level verification, board-level verification with key debounce))

RS（255，223）编码器，已实际运用到产品中(RS (255,223) encoder has actually applied to products)

说明：  该代码，只用了硬件描述语言Verilog在完成对SD卡控制器的编写，经济实用(The code, only the hardware description language Verilog in the completion of the SD card controller to prepare, economical and practical)
