Micro-Operation (Micro-Ops or µOP) is a simpler internal representation of an architectural instruction as handled by the microprocessor. While exact definition of µOPs varies across chip designs 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. While often associated with CISC ISAs such as x86, micro-ops are also used in various RISC designs such as ARM.
