The ARM Cortex-A7 MPCore is a 32-bit microprocessor core licensed by ARM Holdings implementing the ARMv7-A architecture announced in 2011.[1]

Overview

[edit]
The Cortex-A7 is used to power the popular Raspberry Pi 2 micro-computer.
Main article: Comparison of ARMv7-A cores

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.[2] To do this it is fully feature-compatible with the A15.

Key features of the Cortex-A7 core are:

Chips

[edit]

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