The ARM Cortex-A53 is a microarchitecture implementing the ARMv8-A 64-bit instruction set designed by ARM Holdings. The Cortex-A53 is a superscalar processor, capable of dual-issuing some instructions.[1] It is available as SIP core to licensees, and is marketed by ARM as either a stand-alone, more energy-efficient alternative to the more powerful Cortex-A57 microarchitecture, or to be used alongside a more powerful microarchitecture in a big.LITTLE configuration.


  • 8-stage pipelined processor with 2-way superscalar, in-order execution pipeline
  • DSP and NEON SIMD extensions are mandatory per core
  • VFPv4 Floating Point Unit onboard (per core)
  • Hardware virtualization support
  • TrustZone security extensions
  • 64-byte cache lines
  • 10-entry L1 TLB, and 512-entry L2 TLB
  • 4 KiB conditional branch predictor, 256-entry indirect branch predictor


The ARM Cortex-A53 processor has been used in the Raspberry Pi 3 since February 2016.[2]

The Cortex-A53 is also used in a number of Qualcomm Snapdragon SoCs.[3][4] Semi-custom derivatives of the Cortex-A53 have been used in the Kryo 260 CPU.[5]

The processor is used in the ODROID-C2[6] and in Roku streaming media players (in the high-end models from 2016 and in all 2017 models). Another notable Cortex-A53 application is the Pine A64/A64+ single-board computer.
