	The AMD64 (x86-64, x86_64) is the 64bit version of the Intel x86 instruction set.		The AMD64 (x86-64, x86_64) is the 64bit version of the Intel x86 instruction set.

			== Overview ==
			=== Operating Modes ===
			There are 3 modes of operation:
			# Real/Unreal mode: Earliest x86 processors; initial mode on power on.
			# Legacy mode (protected mode, virtual 8086 mode): Runs protected mode operating systems in either 32 or 16bit.
			# Long mode: Primary mode for 64bit processors. Can also run 32 or 16bit compatibility mode.

			=== Registers ===
			There are 16 64bit general registers. While considered these are considered for "general use", some have specific behavior; see notes for more information.
