集成电路的I2C协议间

如果需要用verilog设计一项比较简单的功能，那么这个浅显易懂的程序能让你很快明白点阵的设计方法，尤其是对那些初学者(If you need to use a relatively simple verilog design features, then this easy to understand design of the program allows you to quickly understand the lattice method, especially for those who are beginners)

摘要：本文主要介绍以CPLD 芯片进行十字路口的交通灯的设计，用CPLD 作为交通灯控制器的主控芯片，采用VHDL 语言编写控制程序，利用CPLD的可重复编程和在动态系统重构的特性，大大地提高了数字系统设计的灵活性和通用性。 关键词：CPLD；VHDL；交通灯控制器 中图分类号：TP39 Abstract ：This paper introduces the electronic-traffic lamp, which is based on the VHDL and is completed by-Abstract: This paper introduces the CPLD chip to the traffic lights at the crossroads of design, traffic lights with CPLD as the master controller chip, the use of VHDL language control procedures, the use of CPLD re-programming and dynamic system reconfiguration in the features greatly enhance the digital system design flexibility and versatility. Keywords: CPLD VHDL traffic lights controller CLC number: TP39 Abstract: This paper introduces the electronic-traffic lamp, which is based on the VHDL and is completed by
