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