In other words, the instruction processed by the control unit after dealing with the interrupt signal is the first instruction of the selected handler.

换句话说，控制单元在解决完中断信号后，处理的指令就是选中的处理函数的第一条指令。

Before dealing with that instruction, the control unit checks whether an interrupt or an exception occurred while the control unit executed the previous instruction.

在执行这个指令之前，控制单元检查在它执行前一条指令时，是否有中断或异常产生。

The interrupt instruction passes control to a kernel handler, which after executing a replacement function, returns to continue executing the process.

中断指令将控制传递给内核句柄，后者在执行替换函数执行之后，返回来继续执行该进程。
