X86 vs X64 vs AnyCPU [英] X86 vs X64 vs AnyCPU
问题描述
对 VS 2008 和 2010 中的 X86、X64 和 AnyCPU 配置有点困惑
Have a little confusion on X86 , X64 and AnyCPU configuration in VS 2008 , vs 2010
问题 01
X86 为什么可以在 64 位 windows 7、windows 8 甚至是 64 位操作系统的服务器配置机器上运行?
How come X86 works in 64 bit windows 7 , windows 8 and even the server configuration machines that is in 64 bit OS ?
问题 02
X86 vs X64 vs AnyCPU 有什么明显区别?由于我发现的网络资源令人困惑，因此任何人都可以分别清楚地解释每一个(即 X86、X64 和 AnyCPU).
X86 vs X64 vs AnyCPU what are the clear differences ? can any one explain clearly on each one (i.e. X86, X64 and AnyCPU) separately since the web resources I found are confusing.

因为 WoW64(Windows 64 位).基本上它是一个 32 位模拟器，它允许您在 64 位操作系统中运行 32 位程序.
Because of WoW64 (Windows on Windows 64-bit). Bascially it is a 32 bit emulator, which allows you to run 32 bit programs in a 64 bit operating system.

X86 是 32 位应用程序的模式，以 80x86 系列 CPU 命名.32 位应用程序可以寻址 4 GB 内存.
X86 is the mode for 32 bit applications, named after the 80x86 series CPUs. A 32 bit application can address 4 GB of memory.
X64 是 64 位应用程序的模式，它是名称的缩写 x86-64 这是 x86 指令集的 64 位模式.64 位应用程序可以寻址 18 PB(拍字节)的内存，这意味着所有可用内存(在可预见的未来).
X64 is the mode for 64 bit applications, it's a shortening of the name x86-64 which is the 64 bit mode of the x86 instruction set. A 64 bit application can address 18 PB (petabyte) of memory, which translates to all available memory (for the forseeable future).
AnyCpu 模式允许编译到其他两种模式中的每一种.
The AnyCpu mode allows for compilation to each of the other two modes.
编译模式只是给 JIT 编译器的一个指令，说明如何允许将 IL 代码编译成机器码.IL 代码本身对于所有模式都是相同的.
The compilation mode is just an instruction for the JIT compiler for how it is allowed to compile the IL code into machine code. The IL code itself is the same for all modes.
