可编程中断控制器中断控制器8259A是专门为控制优先级中断而设计开发的芯片。它将中断源优先排队、辨别中断源以及提供中断矢量的电路集于一片中。因此无需附加任何电路，只需对8259A进行编程，就可以管理8级中断，并选择优先模式和中断请求方式，即中断结构可以由用户编程来设定。同时，在不需要增加其他电路的情况下，通过多片8259A的级连，能构成多达64级的矢量中断系统-Programmable Interrupt Controller Interrupt Controller 8259A is designed for control and priority interrupt the core design and development tablets. It will interrupt source priority queuing, identifying the source of disruption and the provision of the circuit interrupt vector set in a Chinese. Thus there is no need for any additional circuit, just right for 8259 A programming, it can manage eight interruption, and to choose the mode and priority interrupt request means that the structure can be interrupted by the user to set programming. At the same time, no additional circuit of the other, through more than 8,259 tablets of class A connected, could constitute up to 64 Vector Interrupt System

本文主要介绍以EP1C3/EP1C6芯片进行十字路口的交通控制灯的设计，该系统可控制2个方向的红、黄、绿三盏灯,让其按特定的规律进行变化。用EP1C3/EP1C6作为交通控制灯的主控芯片，采用VHDL语言编写控制程序，利用MAX+PlusⅡ对设计结果进行仿真，发现系统工作性能良好。据此设计而成的硬件电路,也实现了控制要求。该设计展示了VHDL语言的强大功能和优秀特性。-This paper introduces the crossroads EP1C3/EP1C6 chip design of traffic control lights, the system can control the direction of two red, yellow, green, three lights, let the law be changed according to the specific. As a traffic control light with EP1C3/EP1C6 master chip, using VHDL language control program, using MAX+ Plus Ⅱ design simulation results and found that system works good performance. Accordingly designed with the hardware circuit, also achieved control requirements. The design shows the power of VHDL language and excellent features.
