什么是指令集架构(ISA) [英] What is an Instruction Set Architecture (ISA)

问题描述

我正在尝试找到

指令集和指令集体系结构(如果有区别.)我只能找到技术参考.

instruction set and instruction set architecture (if there is a difference.) I can only find technical references.

如果有人可以在几段中解释它的含义及其对程序员的重要性，我将不胜感激.

I would appreciate if somebody can help explain in a few paragraphs what it is and its importance to a programmer.

推荐答案

指令集将是特定语言的指令集.

Instruction Set would be the repertoire of a particular language.

指令集体系结构()(ISA)是理解库的方式.

Instruction Set Architecture (ISA) is the way that repertoire is understood.

让我们考虑使用汇编语言的人机差异.

Let's think of the differences between human and machine using Assembly Language.

众所周知，机器可以理解零和一，对吗?他们可以比人类更快地了解这个过程.

Machines are known to understand zeros and ones, right? They can understand this process far faster than humans.

人类使用文本表示法来表示这些零和一.(.ORIG，.FILL，.STRINGZ，.END等)

Humans use textual representations to represent these zeros and ones. (.ORIG, .FILL, .STRINGZ, .END, etc)

您能告诉我x61(十六进制)是什么字母吗?可能不会.但是根据其ISA，一台机器会理解x61是字母"a".

Could you tell me what letter is x61 (hexadecimal)? Probably not. But a machine would understand that x61 is the letter 'a' according to its ISA.
