The ARM Cortex-A5 is a 32-bit processor core licensed by ARM Holdings implementing the ARMv7-A architecture.
Overview
<templatestyles src="Module:Hatnote/styles.css"></templatestyles>
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 SAMA5D3
- 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]
