Cortex-A75 (codename Prometheus) is the successor to Cortex-A73, a low-power high-performance ARM microarchitecture designed by ARM Holdings for the mobile market.

This microarchitecture is designed as a synthesizable IP core and is sold to other semiconductor companies to be implemented in their own chips. The Cortex-A75, which implemented the ARMv8.2 ISA, is the a performant core which is often combined with a number of lower power cores (e.g. Cortex-A55) in a DynamIQ big.LITTLE configuration to achieve better energy/performance.

Compiler support

Compiler	Arch-Specific	Arch-Favorable
Arm Compiler	-mcpu=cortex-a75	-mtune=cortex-a75
GCC	-mcpu=cortex-a75	-mtune=cortex-a75
LLVM	-mcpu=cortex-a75	-mtune=cortex-a75

If the Cortex-A75 is coupled with the Cortex-A55 in a big.LITTLE system,

GCC also supports the following option:

Compiler	Tune
GCC	-mtune=cortex-a75.cortex-a55
