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:


Several system-on-chips (SoC) have implemented the Cortex-A5 core, including:
