Overview

Main article: Comparison of ARMv7-A cores

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:

• Actions Semiconductor ATM7029 (gs702a) is a quad-core Cortex-A5 configuration
• AMD APUs include a Cortex-A5 as a security co-processor^[3]
• Amlogic S805, M805 and A111
• Analog Devices ADSP-SC57x, ADSP-SC58x series ARM Cortex-A5 + SHARC+ multicore DSP
• Atmel SAMA5Dxx
• Freescale Vybrid Series
• NTC Module 1879VM8Ya (penta-core Cortex-A5, up to 800 MHz)
• Qualcomm Snapdragon S1 MSM7x25A / MSM7x27A (up to 1.0GHz + Adreno 200)
• Qualcomm Snapdragon S4 Play
• Samsung Exynos 7420 (Cortex-A5 as an audio DSP)^[4]
• Spreadtrum SC8810 (single core A5 1 GHz + Mali400 GPU)
• All AMD CPUs since the Zen microarchitecture^{[needs update?]} contain a Cortex-A5 as a Platform Security Processor^[5]
