The design method of traffic light control system by using Very-High-Speed Integrated Circuit(VHSIC) Hardware Description Language ( VHDL ) is introduced, and the downloading of the controller design to the FPGA / CPLD chip in MAX + PLUS II is fulfilled. 用VHDL语言设计交通灯控制系统,并在MAX+PlusII系统对FPGA/CPLD芯片进行下载,由于生成的是集成化的数字电路,没有传统设计中的接线问题,所以故障率低、可靠性高,而且体积小。
Introduce production line technology, employ Field-Programmable Gate Array ( FPGA ) and use Very-High-Speed Integrated Circuit(VHSIC) Hardware Description Language ( VHDL ) to realize data encryption and deciphering. 3. 引入流水线技术,采用可编程门阵列(FPGA),基于超高速集成电路(VHSIC)硬件描述语言(VHDL)来实现数据的加解密。
