Editing x86

{{x86 isa main}}
'''x86''' is a family of [[little-endian]], [[variable-length]], [[instruction set architectures]] and [[instruction set architectures extension|extensions]]. As its namesake indicates, the x86 ISA offers [[binary compatibility]] all the way from the original {{intel|8086}} to modern [[microarchitecture]]s as well as [[source code compatibility]] since the {{intel|8080}}. The x86 architecture is widely used in the [[desktop]] and [[server]] markets. Today, custom x86-based implementations are designed by a number of [[semiconductor companies|companies]] including [[Intel]], [[AMD]], [[VIA]], [[Zhaoxin]], [[DM&P]], and [[RDC Semiconductors|RDC]].

Generally speaking, the term 'x86' is most often used as an umbrella term encompassing the original {{x86|x86-16}}, {{x86|x86-32}} (IA-32), {{x86|x86-64}} (AMD64), and the various extensions such as {{x86|MMX}}, {{x86|3DNOW!}}, and {{x86|SSE}}.
