In 64 bits, this number increases to 2^64-1, or 18,446,744,073,709,551,615.More specifically, 64 bits is the size of the registers on a 64-bit CPU's microprocessor or the computer bus.64-bit hardware, and the software compiled to run on it, is sometimes called x86-64. This ...
Intel has been floating the idea of cutting all the non-64-bit stuff in x86 to create the tentatively named x86S architecture. This would theoretically result in better performance and efficiency, and although not having 32-bit support was a bad idea back ...

On the other hand, AMD designed thex86-64 processor, which ran both 32-bit software at native hardware speed and offered support to 64-bit memory (AMD64). This is called as x86-64 or now simply as x64. x64 is actually a Microsoft term and stands for Extended 64. While initially, M...
The terms "x64" and "x86" refer to different computer architectures used in modern processors. They indicate whether the processor and the operating system are 64-bit or 32-bit, respectively. Understanding the difference between x64 and x86 is essential when installing software, choosing an opera...
But why does x64 refers to a 64-bit system while x86 refers to a 32-bit system? That was the question I asked myself too at first. However, this is because as when the processor was first being created, it was called 8086. The 8086 was well designed and popular which can understand...

CPU 有一个专用的寄存器(x86-64 上为 CR3),保存着最高级(即 4 级)页表(PML4)的物理地址。 从PML4 到 Page-Table Offset 的四个部分是各级页表的索引。第 4 级到第 2 级目录的内容是对下一级目录的引用。如果一个目录条目被标记为空,它显然不需要指向任何较低的目录。这样页表树就可以稀疏紧凑。每一...
