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

very nice program that i ensure anyone can use easily and will be efficient for hard project of elevator

用于FPGA的学习，大家值得借鉴，可以好好学习一下(this is for fpga and you can use this.)

说明：  基于fpga状态机的交通灯设计，亮灯时间自己修改，程序简单易懂。(Traffic light design based on FPGA state machine, light time self-modifying, the program is simple and easy to understand.)

输入的8X8图像数据块包括在范围从0到255的整数。在DCT计算的平均值减去128从输入数据中最小的输入数据块的冗余。核心可以计算输入数据的范围128到127以及–。然后，平均值128不减。在DCT的计算，数据可以减少到重要的信息集中到少数的DCT结果，留下剩余的系数等于零。这意味着图像的能量集中 请点击左侧文件开始预览 ！预览只提供20%的代码片段，完整代码需下载后查看 加载中 侵权举报
