TheARM Cortex-A7 MPCore is a 32-bit microprocessor core licensed byARM Holdings implementing theARMv7-A architecture announced in 2011.^[1]

Overview

[edit]

The Cortex-A7 is used to power the popularRaspberry 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 theCortex-A8. The other use is in thebig.LITTLE architecture, combining one or more A7 cores with one or moreCortex-A15 cores into aheterogeneous system.^[2] 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-stagepipeline^[3]
NEON SIMD instruction set extension
VFPv4 Floating Point Unit
Thumb-2 instruction set encoding
Jazelle RCT
Hardware virtualization
Large Page Address Extensions (LPAE)
Integrated level 2 Cache (0–1 MB)
1.9DMIPS / MHz^[3]
Typical clock speed 1.5 GHz^[3]
