INTEL系列微处理器的中断处理技术

Interrupt Processing Technique of Intel Microprocessor Series

给出了微机采用中断传送方式编写程序的三种方法 :循环踏步等待中断、外部硬件中断与软件系统同步、中断接管和热键技术。通过一个实例介绍使用热键 Ctrl F1 1激活驻留程序 ,在屏幕上显示系统时间 ,也可用热键 Ctrl F1 2关闭时钟显示。

This paper introduces three ways to design interrupt program in microprocessors,loop crippled wait interrupt,external hardware interrupt synchronizes with software system,interrupt taking over and hot key technique.The example is given that a resident program is activated through hot key CtrlF11,and system time is displayed in the screen and the clock display also can be stroked by CtrlF12.
