In [[electronics]], [[computer science]] and [[computer engineering]], '''microarchitecture''', also called '''computer organization''' and sometimes abbreviated as '''μarch''' or '''uarch''', is the way a given [[instruction set architecture]] (ISA) is implemented in a particular [[Central processing unit|processor]].<ref>{{cite book
