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.

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:

Partial dual-issue, in-order microarchitecture with an 8-stage pipeline^[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)
1.9 DMIPS / MHz^[3]
Typical clock speed 1.5 GHz^[3]

Chips[edit]

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

Allwinner A20 (dual-core A7 + Mali-400 MP2 GPU)^[4]
Allwinner A31 (quad-core A7 + PowerVR SGX544MP2 GPU)^[5]
