'''Micro-Operation''' ('''Micro-Ops''' or '''µOP''') is a simple 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]], micro-ops are also used in various [[RISC]] designs such as [[ARM]] and [[POWER]].
