The AMD x86-64
TM
Architecture
The AMD x86-64 architecture extends the legacy x86 architecture by introducing two major
features: a 64-bit extension called
long mod
e, and register extensions.
Long Mode
Long mode consists of two sub-modes:
64-bit mod
e, and
compatibility mod
e. Compatibility
mode supports binary compatibility with existing 16-bit and 32-bit applications under a 64-bit
operating system. In addition to long mode, the architecture also supports a pure x86
legacy
mod
e, which preserves binary compatibility not only with existing 16-bit and 32-bit applications
but also with existing 16-bit and 32-bit operating systems.
64-Bit Mode
64-bit mode supports the following new features:
64-bit virtual addresses (implementations can have less).
Register extensions through a new prefix (REX):
o
Adds eight GPRs (R8–R15).
o
Widens GPRs to 64 bits.
o
Adds eight 128-bit Streaming SIMD Extension (SSE) registers (XMM8–
XMM15).
64-bit instruction pointer (RIP).
