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. 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.
