Verilog HDL编写的CPU模型，很经典，比较通用

用来实现IRIG_B码的解码程序，在XILINX ISE上运行过没有问题，(Used to achieve IRIG_B code decoding process, in XILINX ISE run-off is no problem,)

试设计一种彩灯控制器控制8盏灯。该彩灯控制器有4种自动切换的花样。第一种花样为彩灯从右到左，然后从左到右逐次点亮，全灭全亮；第二种花样为彩灯两边同时亮一个逐次向中间移动再散开；第三种花样为彩灯两边同时亮两个逐次向中间移动再散开；第四种花样为彩灯两边同时亮三个，然后四亮四灭，四灭四亮，最后一灭一亮。四个花样自动变换，重复以上过程。输入时钟频率为500Hz，灯亮的时间在1―4秒之间，可以自由控制。电路中以“1”代表灯亮，以“0”代表灯灭。-Lantern try to design a controller to control 8 lights. The controller has four kinds of lanterns automatically switch the pattern. The first lantern pattern for right-to-left, and then lit from left to right each time, the whole body light second pattern for a lantern light at the same time on both sides of successive spread to the middle of moving again third pattern for lantern light at the same time on both sides to the middle of two successive re-dispersed mobile fourth pattern for the lantern light at the same time on both sides of the three, then four out four bright, four out four-liang, the last light out. Automatically transform the four patterns, repeat the process above. Input clock frequency of 500Hz, the time for lights between 1-4 seconds, they can con
