Editing micro-operation

{{title|Micro-Operation (µOP)}}
'''Micro-Operation''' ('''Micro-Ops''' or '''µOP''') is a simple [[internal operation|internal]] representation of an [[architectural instruction]] as handled by the [[microprocessor]]. While exact definition of µOPs varies across implementations it is generally associated with designs that transform more complex (e.g. variable length or multiple operations) instructions with simple single-operation commands. Generally, Micro-Operations are a result of [[cracking]] [[Macro-Operations]]. It's a common misconception that micro-operations are exclusively a [[CISC]] concept. While more often associated with [[CISC]] [[ISA]]s such as [[x86]] and [[z/Architecture]], micro-ops are also used in various [[RISC]] designs such as [[ARM]] and [[POWER]].

== Nomenclature ==
* [[Intel]] refers to the [[internal operations]] of fixed length, regular format, and encoding a ''micro-operation''. Those are a result of decoded [[macro-operations]].
* [[AMD]] refers to the simple, single-operation (e.g. a single arithmetic or memory operation) a ''micro-operation''. Those µOPs makes up a potentially more complex [[macro-operation]].
* [[ARM Holdings|ARM]] refers to the [[internal operations|internal]] representation of instructions as ''micro-operation''. Those are a result of decoded instructions or may be part of a group of µOPs as [[macro-operation]].
