x86-64 (also known as x64, x86_64, AMD64, and Intel 64) is a 64-bit version of the x86 instruction set, first announced in 1999. It introduced two new modes of operation, 64-bit mode and compatibility mode, along with a new 4-level paging mode.
Em informática, x86 ou 80x86 é o nome genérico dada à família (arquitetura) de processadores baseados no Intel 8086, da Intel Corporation. [1] [2] A arquitetura é chamada x86 porque os primeiros processadores desta família eram identificados somente por números terminados com a sequência "86": o 8086, o 80186, o 80286, o 80386 e o 80486.
x86-64 is the 64-bit extended architecture of x86, its Legacy Mode preserves the entire and unaltered x86 architecture.
The x86 instruction set refers to the set of instructions that x86-compatible microprocessors support. The instructions are usually part of an executable program, often stored as a computer file and executed on the processor.
AMD64 (também conhecido como x64, x86_64, x86-64 e Intel 64), em informática, é o nome genérico dado à família (arquitetura) de processadores baseados na tecnologia de 64 bits desenhado pela empresa Advanced Micro Devices (AMD), utilizada pelos processadores da AMD, da Intel, da VIA, e outros. É um superconjunto da arquitetura x86.
AMD publicly discloses its set of 64-bit extensions to IA-32, called x86-64 (later branded AMD64). 2000 IBM ships its first 64-bit z/Architecture mainframe, the zSeries z900. z/Architecture is a 64-bit version of the 32-bit ESA/390 architecture, a descendant of the 32-bit System/360 architecture. 2001
x86 assembly language is the name for the family of assembly languages which provide some level of backward compatibility with CPUs back to the Intel 8008 microprocessor, which was launched in April 1972. [1] [2] It is used to produce object code for the x86 class of processors.
