x8664Amd64
x86-64, also known as AMD64, is a 64-bit extension to the x86 instruction set developed by AMD. It was introduced in 2003 with the Opteron and Athlon 64 processors and quickly became the industry standard for 64-bit x86 computing. The design preserves backward compatibility with 16- and 32-bit x86 software, providing a long mode that enables native 64-bit execution while offering a compatibility mode to run 32-bit code.
A key feature of x86-64 is its expanded general-purpose registers, now including rax, rbx, rcx, rdx, rsi,
The instruction set has been extended with numerous enhancements, including advanced vector extensions (SSE, SSE2, and
Adoption and naming: AMD64 is widely used in desktops, laptops, and servers. Intel adopted the same extension,
