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. To do this it is fully feature-compatible with the A15. Key features of the Cortex-A7 core are: * Partial dual-issue, in-order microarchitecture with an 8-stage
