Are you someone that is confused by terms like ARM, AArch64, x86_64, i386, etc when viewing a datasheet or downloads page of a software? These are called CPU architecture
| CPU Architecture | Description | |
|---|---|---|
| X86 | 32位 | 英特尔出的处理习惯以86为结尾，如80186、80286、80386，所以之后被称之为 X86 |
| AMD64 | 64位 | 32位向64位演进时，AMD 抢先制造出了兼容 X86 32位指令集的 64位处理器 |
X86-64 | 64位 | 64-bit Intel CPUs 因特尔设计 IA-64，比amd晚了一步，且不兼容 X86 32位指令集，比较惨淡 |
| ARM | ARM CPUs 适用于移动通信这种低成本、高性能、低耗电的领域 | |
| ARM-V8 | AArch64：64位执行状态 AArch32：32位执行状态 | ARM CPUs 有两种执行态，适用于 32位和64位 |
| AArch64 | 64位 | 从 ARM-V8 中独立出来 |
