基于CORDIC算法的FFT
- 采用按时间抽选的基4原位算法和坐标旋转数字式计算机（CORDIC）算法实现了一个FFT实时谱分析系统。-time selected by using the four-situ algorithm and coordinate rotation digital computer (CORDIC) algorithm is one is a real-time FFT spectrum analysis system.
脉冲记时CPLD
- 工作原理： 脉冲输入，记录30个脉冲的间隔时间（总时间），LED显示出来，牵涉到数码管的轮流点亮，以及LED的码。输入端口一定要用个 74LS14整一下，图上没有。数码管使用共阴数码管。MAXPLUS编译。 测试时将光电门的信号端一块连接到J2口的第三管脚，同时第一管脚为地，应该与光电门的地连接（共地）。 开始测试： 按下按键，应该可以见到LED被点亮，指示可以开始转动转动惯量盘，等遮光片遮挡30次光电门后， LED熄灭，数码管有数字显示，此为时间值，单位为秒，与智

LEDWALK
- 走马灯，又名马骑灯，是中国传统玩具之一，灯笼的一种，常见于元夕、元宵、中秋等节日。灯内点上蜡烛，烛产生的热力造成气流，令轮轴转动。轮轴上有剪纸，烛光将剪纸的影投射在屏上，图象便不断走动。因多在灯各个面上绘制古代武将骑马的图画，而灯转动时看起来好像几个人你追我赶一样，故名走马灯。走马灯内的蜡烛需要切成小段，放入走马灯时要放正，切勿斜放。走马灯VHDL代码 非常有用非常有用！-Revolving door, also known as Maji lights, is one of the tradi
