The ARM Cortex-A5 is a 32-bit processor core licensed by ARM Holdings implementing the ARMv7-A architecture announced in 2009.^[1]

Overview

The Cortex-A5 is intended to replace the ARM9 and ARM11 cores for use in low-end devices.^[1] The Cortex-A5 offers features of the ARMv7 architecture focusing on internet applications e.g. VFPv4 and NEON advanced SIMD.^[2]

Key features of the Cortex-A5 core are:

Single-issue, in-order microarchitecture with an 8-stage pipeline^[1]
NEON SIMD instruction set extension (optional)
VFPv4 floating-point unit (optional)
Thumb-2 instruction set encoding
Jazelle RCT
1.57 DMIPS / MHz

Chips

Several system-on-chips (SoC) have implemented the Cortex-A5 core, including:

Atmel SAMA5Dxx
Freescale Vybrid Series
Snapdragon S1 MSM7x25A / MSM7x27A (up to 1.0GHz + Adreno 200)
Snapdragon S4 Play
Spreadtrum SC8810 (single core A5 1 GHz + Mali400 GPU)
Actions Semiconductor ATM7029 (gs702a) is a quad-core Cortex-A5 configuration
2013 AMD Fusion APUs include a Cortex-A5 as a security co-processor^[3]
Samsung Exynos 7420 (Cortex-A5 as an audio DSP)^[4]
