What devices use ARM Cortex-A high-efficiency cores?

ARM Cortex-A high-efficiency cores are integrated into SoCs by manufacturers like Qualcomm, Samsung, and MediaTek, powering Android smartphones, tablets, and embedded systems. They are also used in low-power servers and other energy-efficient computing applications.

How do ARM Cortex-A high-efficiency cores differ from other ARM Cortex families?

Cortex-A high-efficiency cores are optimized for low-power applications, focusing on energy efficiency rather than raw performance. They are distinct from Cortex-R (real-time systems) and Cortex-M (embedded microcontrollers), which serve different use cases.

Are ARM Cortex-A high-efficiency cores 32-bit or 64-bit?

Cortex-A high-efficiency cores support both 32-bit (ARMv7-A) and 64-bit (ARMv8-A) architectures, with later models like Cortex-A53 and A55 supporting 64-bit while remaining backward-compatible with 32-bit code.

Can I buy a standalone ARM Cortex-A high-efficiency processor?

No, ARM delivers synthesizable RTL and documentation, and licensees integrate the core into their own chips, choosing fabrication partners like TSMC or Samsung. You cannot purchase a standalone Cortex-A high-efficiency processor.

What licensing options are available for ARM Cortex-A high-efficiency cores?

ARM offers three license tiers: POP (optimized physical implementation), standard core (RTL plus testbench), and architecture (rights to design custom cores compatible with the ARM ISA).
