Cortex-A9 is the successor to the Cortex-A8, a low-power 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-A9 was later succeeded by four independent lines - high-performance (A15), mainstream performance (A12), high efficiency (A7), and ultra-low power (A5).
