'''Cortex-A8''' (codename '''Tiger''') is the successor to the {{armh|ARM11|l=arch}}, a low-power performance [[ARM]] [[microarchitecture]] designed by [[ARM Holdings]] for the mobile market. This microarchitecture is designed as an [[IP core]] and is sold to other semiconductor companies to be implemented in their own chips. The Cortex-A8 was designed by the Arm Austin design center. | '''Cortex-A8''' (codename '''Tiger''') is the successor to the {{armh|ARM11|l=arch}}, a low-power performance [[ARM]] [[microarchitecture]] designed by [[ARM Holdings]] for the mobile market.
