Revision as of 07:36, 29 May 2017

Cortex-A55 is an ultra-high efficiency microarchitecture designed by ARM Holdings as a successor to the Cortex-A53. The Cortex-A55, which implemented the ARMv8 ISA, is typically found in entry-level smartphone and other embedded devices. Often A55 cores are combined with higher performance processors (e.g. based on Cortex-A57 or Cortex-A725z) in big.LITTLE configuration to achieve better energy/performance.

Note that this microarchitecture is designed as a synthesizable IP core and is sold to other semiconductor companies to be implemented in their own chips.
