Common Functions of Interrupts 中断的常见功能 Interrupts transfers control to the interrupt service routine generall through the interrupt vector, which contains the addresses of all the service routines 通常中断通过中断矢量把控制传送给中断服务程序,该中断矢量包含了所有 服务程序的地址 Interrupt architecture must save the address of the interrupted instruction.中断体系结构必须保护被中断指令的地址 Incoming interrupts are disabled while another interrupt is being processed to prevent a lost interrupt 当另一个中断正在处理时,刚进入的中断不能作用,以免丢失中断 e A trap is a software-generated interrupt caused either by an error or a user request陷阱是由于出错或用户请求引起的软件生成的中断 An operating system is interrupt driven 操作系统是中断驱动的 Applied Operating System Concepts 2.4Applied Operating System Concepts 2.4 Common Functions of Interrupts 中断的常见功能 • Interrupts transfers control to the interrupt service routine generally, through the interrupt vector, which contains the addresses of all the service routines. 通常中断通过中断矢量把控制传送给中断服务程序，该中断矢量包含了所有 服务程序的地址 • Interrupt architecture must save the address of the interrupted instruction. 中断体系结构必须保护被中断指令的地址 • Incoming interrupts are disabled while another interrupt is being processed to prevent a lost interrupt. 当另一个中断正在处理时，刚进入的中断不能作用，以免丢失中断 • A trap is a software-generated interrupt caused either by an error or a user request.陷阱是由于出错或用户请求引起的软件生成的中断 • An operating system is interrupt driven. 操作系统是中断驱动的
