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