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

Overview

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

Key features of the Cortex-A5 core are: Single-issue, in-order microarchitecture with an 8-stage pipeline 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 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) Spreadtrum SC8810 (single core A5 1 GHz + Mali400 GPU) contain a Cortex-A5 as a Platform Security Processor
