History

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.

Digital Video Recorder User Manual 2 CAUTION Please read this user manual carefully to ensure that you can use the device correctly and safely We do not warrant all the content is correct. The contents of this manual are subject to change without notice This device should be operated only from the type of power source indicated on the marking label.

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]
NEONSIMD instruction set extension
VFPv4 Floating Point Unit
Thumb-2 instruction set encoding
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]
