SDRAM控制器设计代码，我们写的SDRAM控制器是肯定包括初始化、读操作、写操作及自动刷新这些操作的，既然这样，我们就可以给每一个操作写上一个模块独立开来，这样也便于我们每个模块的调试，显然这种思路是正确的。那怎么让我们的各个模块工作起来呢，虽然都是独立的模块，但很显然这几个模块之间又是相互关联的。就拿上面刚才说的那个情况来讲，如果SDRAM需要刷新了，而SDRAM却正在执行写操作，那我们刷新模块与写模块之间怎么进行控制呢？这个问题解决了，读模块与刷新模块之间的这个问题也可以很轻松的解决。

说明：  本代码是控制DS1302的VHDL代码，浅显易懂，方便修改，注意看data sheet，保证时钟和各个延迟满足要求即可(This code is to control the DS1302' s VHDL code, easy to understand, easy changes, note the data sheet, ensure the clock and can meet the requirements of the various delays)

例程是基于quartus的，FPGA通过EMIF给DSP发送数据，里面包含了一个简单的状态机和一个基于IP核的fifo，适合初学者(Routine is the FPGA to send data to the DSP via EMIF, which contains a simple state machine and an IP-based core fifo, suitable for beginners)

若农场路无车辆，则在高速路保持绿灯。在探测农场路有车辆，高速路上的交通灯应由绿到黄，再到红，并允许农场路方向灯变绿，绿灯亮一段时间，由绿变黄再到红。(If there is no vehicle on the farm road, keep the green light on the highway. There are vehicles on the farm road, the traffic lights on the high speed road should be green to yellow, and then red, and allow the farm road lights to turn green, the green light for a period of time, from green to yellow, then to red.)
