本实验设计一个十字路口的交通灯控制器，分为东西和南北两个部分。每个部分有五盏灯，分别为左转灯、直行灯、右转灯、人行道灯及黄灯，另外还有一个倒计时器。左转灯、直行灯、右转灯、人行道灯亮表示允许通行，灯灭表示禁止通行；黄灯亮表示即将有信号灯的状态发生改变；倒计时显示了到下一状态的时间。 2.状态表(0表示灯灭，1表示灯亮) 时间度量 东西方向 　南北方向 东西方向 南北方向 t/s ← ↑ → 行人 黄 ← ↑ → 行人 黄 倒计时/s 倒计时/s 0~13 0 1 1 0 0 0 0 0 0 0 13 45 13~15 0 1 1 0 1 0 0 0 0 0 2 　 15~28 0 1 0 1 0 0 0 0 0 0 13 　 28~30 0 1 0 1 1 0 0 0 0 0 2 　 30~43 1 0 0 0 0 0 0 0 0 0 13 　 43~45 1 0 0 0 1 0 0 0 0 0 2 　 45~58 0 0 0 0 0 0 1 1 0 0 45 13 58~60 0 0 0 0 0 0 1 1 0 1 　 2 60~73 0 0 0 0 0 0 1 0 1 0 　 13 73~75 0 0 0 0 0 0 1 0 1 1 　 2 75~88 0 0 0 0 0 1 0 0 0 0 　 13 88~90 0 0 0 0 0 1 0 0 0 1 　 2 3.状态图(低电平表示灯灭，高电平表示灯亮) 4.顶层设计图 如图所示，交通灯控制器主要分为三个模块，交通灯状态控制，交通灯显示和倒计时。交通灯状态控制模块：接受频率为1Hz的时钟信号，根据该信号进行处理，对交通灯显示和倒计时模块给出相应的状态编号(12个状态)。交通灯显示模块：通过相应的状态设置两组交通灯的亮灭。倒计时模块：通过相应的状态确定倒计时的基数及显示。
