Cortex-A76 (codename Enyo) is the successor to the Cortex-A75, 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-A76, 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.

Overview
The Cortex-A76 is a high-performance synthesizable core designed by Arm as the successor to the Cortex-A75. It is delievered as Register Transfer Level (RTL) description in Verilog and is designed. This core supports the ARMv8.2 extension as well as a number of other partial extensions. The A76 is a 4-way superscalar out-of-order processor with a private level 1 and level 2 caches. It is designed to be implemented inside the DynamIQ Shared Unit (DSU) cluster along with other cores (e.g., with little cores such as the Cortex-A55)
