摘要
本文采用自顶向下的设计方法,利用可编程逻辑器件CPLD实现一个基于VHDL语言编写的交通灯控制系统,通过外部输入可方便地设定交通灯的延迟时间,使交通灯控制数字电路设计得到了优化,提高了系统的灵活性、可靠性和可扩展性。该系统可以较好地缓解交通压力,并可实现对突发事件进行紧急处理。
The paper adopts the design method from top to bottom, Using FPGA to design control system of traffic light based on the VHDL language .Time of traffic light is set easily by exterior input .It make design of numeric circuit optimized, advancing design agility, dependability and expansibility. It also reduces press of traffic, emergently dealing with gusty traffic accidences.
