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:

  • 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
  • Samsung Exynos 7420 (Cortex-A5 as an audio DSP)
