ARM Cortex-A53

  (Redirected from Cortex-A53)

The ARM Cortex-A53 is one of the first two microarchitectures 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 was announced October 30th, 2012[2] 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.

  • 64-byte cache lines
  • 10-entry L1 TLB, and 512-entry L2 TLB
  • 4 KiB conditional branch predictor, 256-entry indirect branch predictor

UtilizationEdit

The ARM Cortex-A53 processor has been used in the LeMaker HiKey since 2015[3] and Raspberry Pi 3 since February 2016.[4]

The Cortex-A53 is also used in a number of Qualcomm Snapdragon SoCs.[5][6] Semi-custom derivatives of the Cortex-A53 have been used in the Kryo 260 CPU.[7]

The processor is used in the ODROID-C2[8] 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.

These cores are used in a 24-core SoC, the Socionext SynQuacer SC2A11.

The processor is used in Amazon Fire tablets, like the Fire HD8.
