Succession

Cortex-A17 is the successor to the Cortex-A12, 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-A17 was designed to be paired with the low-power Cortex-A7 in a big.LITTLE configuration.
