Cortex-A7 (codename Kingfisher) is the successor to the Cortex-A9, a high efficiency 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-A7 was introduced along with the big.LITTLE technology so that it could be integrated along with the a higher-performance core such as the Cortex-A15 or the Cortex-A17 for better energy and power efficiency.
