| − | '''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]]. | + | '''x86''' is a family of [[little-endian]], [[variable-length]], [[instruction set architectures]] and [[instruction set architectures extension|extensions]].
