中断和例外 [英] Interrupts and exceptions

问题描述

我在这里看到关于例外情况的几个问题，还有一些他们暗示中断作为例外情况，但没有使连接清除。

I've seen several question on here about exceptions, and some of them hint at interrupts as exceptions, but none make the connection clear.

• 什么是中断？

• What is an interrupt?

有什么例外？ （请说明您所了解的每种语言的例外情况，因为有一些差异）

What is an exception? (please explain what exceptions are for each language you know, as there are some differences)

什么时候中断是异常的？反之亦然？ >

When is an exception an interrupt and vice-versa?

推荐答案

中断是由硬件或特定CPU指令生成的CPU信号。这些导致中断处理程序被执行。诸如来自I / O硬件的I / O信号等事件会产生中断。

An interupt is a CPU signal generated by hardware, or specific CPU instructions. These cause interupt handlers to be executed. Things such as I/O signals from I/O hardware generate interupts.

异常可以被认为是中断的软件版本，仅影响其进程

An exception can be thought of as a software-version of an interupt, that only affects its process.

我不确定具体的细节，但可以通过中断来执行例外 。

I'm not sure on the exact details, but an exception could be implemented by an interupt.
