The ARM Cortex-A7 MPCore is a 32-bit microprocessor core licensed by ARM Holdings implementing the ARMv7-A architecture announced in 2011.

Overview

It has two target applications; firstly as a smaller, simpler, and more power-efficient successor to the Cortex-A8. The other use is in the big.LITTLE architecture, combining one or more A7 cores with one or more Cortex-A15 cores into a heterogeneous system.[1] To do this it is fully feature-compatible with the A15.

Key features of the Cortex-A7 core are:

Chips

Several system-on-chips (SoC) have implemented the Cortex-A7 core, including:
