About the core

The Cortex®‑A76 core is a high-performance and low-power Arm product that implements the Arm®v8‑A architecture.

The Cortex‑A76 core supports:

  • The Armv8.2‑A extension.
  • The RAS extension.
  • The Load acquire (LDAPR) instructions introduced in the Armv8.3‑A extension
  • The Dot Product instruction support introduced in the Armv8.4‑A extension.
  • The PSTATE Speculative Store Bypass Safe (SSBS) bit and the speculation barriers (CSDB, SSBB, PSSBB) instructions introduced in the Armv8.5‑A extension.

The Cortex‑A76 core has a Level 1 (L1) memory system and a private, integrated Level 2 (L2) cache. It also includes a superscalar, variable-length, out-of-order pipeline.

The Cortex‑A76 core is implemented inside the DynamIQ™ Shared Unit (DSU) cluster. For more information, see the Arm® DynamIQ™ Shared Unit Technical Reference Manual.

The following figure shows an example of a configuration with four Cortex‑A76 cores.
