Succession

Cortex-A53 (formerly Apollo) is an ultra-high efficiency microarchitecture designed by ARM Holdings as a successor to the Cortex-A7. The Cortex-A53, which implemented the ARMv8 ISA, is typically found in entry-level smartphone and other embedded devices. Often A53 cores are combined with higher performance processors (e.g. based on Cortex-A57 or Cortex-A72) 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.

Compiler support[edit]

Compiler Arch-Specific Arch-Favorable Arch-Target
GCC -march=armv8-a -mtune=cortex-a53 -mcpu=cortex-a53
LLVM -march=armv8-a -mtune=cortex-a53 -mcpu=cortex-a53

Note that for big.LITTLE systems it's possible to specify more specific performance tunes:

  • -mtune=cortex-a57.cortex-a53
  • -mtune=cortex-a72.cortex-a53
  • -mtune=cortex-a73.cortex-a53
