'''ARM9''' is the successor to the {{armh|ARM8|l=arch}}, a low-power performance [[ARM]] [[microarchitecture]] designed by [[ARM Holdings]] for the mobile market. This microarchitecture is designed as a synthesizable [[IP core]] and is sold to other semiconductor companies to be implemented in their own chips.
