VHDL 状态机的设计实例 ,不错的,对于搞清楚状态机是很有用的....

8255参考设计VHDL源代码-The sound code of 8255 reference design based on VHDL

first in first out 的说明文档以及时序图 对学习FIFO很有帮助(first in first out the documentation and the timing diagram helpful in learning FIFO)

和picoblaze完全兼容的mcu ip core-And PicoBlaze fully compatible mcu ip core

使用FPGA测量频率大小，并且在数码管上进行显示(Frequency measurement using FPGA and display on digital tube)

通过上翻键和下翻键来设置方波信号正负脉冲宽度，利用一排流水灯来显示按键的次数，通过观察流水灯亮的盏数确定占空比（按一次上翻键亮一盏灯，流水灯全亮时占空比调到了最高或者是最低状态，按一次下翻键灭一盏灯，流水灯全灭时占空比调到了最低或者是最高状态）。(Duty cycle of LED lights and adjustable oscilloscope display code)
