基于FPGA的乡村交通灯的设计

The Design of Country Traffic Lights Based on FPGA

文章介绍了一种基于Altera公司的Cyclone系列现场可编程门阵列FPGA的乡村小路交通灯的设计。根据该十字路口的特殊情况，分析其所有的状态及转换，并用硬件描述语言VHDL对其状态机、计数器和译码器进行设计，运用软件MAX＋PLUSII仿真后下载到EPIC3T44中，在所设计的电路中实现。

This paper provides a design of country traffic lights based on Cyclone FPGA of Altera company. It analyzes all the states and their transfer sequences in accordance with the special situation of the traffic, and programs its state machine, counter and decoder. Then the programs are simulated and downloaded to the real chip.
