Cortex-A12 (codename Owl) is the successor to the Cortex-A9, a mid-range 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. The Cortex-A12 was designed to be paired with the low-power Cortex-A7 in a big.LITTLE configuration.
Note that Arm withdrew the Cortex-A12 from their product offering in October 2014 due to having design and performance parameters very similar to its successor, the Cortex-A17.
