说明：  通过循环读写DDR3内存，了解其工作原理和DDR3控制器的写法，由于DDR3控制复杂，控制器的编写难度高，这里笔者介绍XILINX的MIG控制器情况下应用，是后续音频、视频等需要用到SDRAM实验的基础。(Through reading and writing DDR3 memory circularly, we can understand its working principle and the writing method of DDR3 controller. Because of the complexity of DDR3 control, it is difficult to write the controller. Here, the author introduces the application of Xilinx's MIG controller, which is the basis of SDRAM experiment for subsequent audio and video.)

设计一个由一条主干道和一条支干道的汇合点形成的十字交叉路口的交通灯控制器： 1)       主、支干道各设有3个方向的绿、黄、红指示灯（左转、直行和右转），每个行驶方向均配有时间显示数码管；2)       主干道处于常允许通行状态，而支干道有车来才允许通行（由外部信号通知）。3)       当主、支道均有车时，两者交替允许通行，主干道每次放行90s，支干道每次放行60s，在每次由亮绿灯变成亮红灯的转换过程中，要亮5s黄灯作为过渡，并进行减计时显示。
