Cortex-A15 (codename Eagle) is the successor to the Cortex-A9, a low-power high-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 A15 is the first microarchitecture specifically designed for high-performance, whereas the Cortex-A12 (and the A17), also the successor to the Cortex-A9, target high-efficiency.
