Editing Machine instruction

A '''machine instruction''' is

{{Quote|an instruction that is written in a [[machine language]] and can be [[execute]]d directly by the [[processor]] for which it was designed without [[translation]] or [[interpretation]].<ref>[http://www.atis.org/glossary/definition.aspx?id=3878 ATIS Telecom Glossary 2007.]</ref>}}

== Overview ==

"Machine instructions are specific to the [[instruction set architecture]] ([[ISA]]) that a given [[computer architecture]] or [[architecture]] family [[implement]]s. For a given [[high-level program]], the machine instruction count varies when it [[execute]]s on different [[computer system]]s because of differences in the underlying [[ISA]], in the [[microarchitecture]] that [[implement]]s the [[ISA]], and in the [[tool]]s used to [[compile]] the [[program]]."<ref>[[The Future of Computing Performance: Game Over or Next Level?]], at 60.</ref>
