Cortex-A Characteristics

All Cortex-A based processors share a commonly supported architecture and feature set. Armv7-A processors support a 32-bit instruction set and data path as well as the mixed 16/32-bit Thumb2 instruction set. Armv8-A Cortex-A processors add support for the AArch32/AArch64 execution states. Armv8.2-A Cortex-A processors add architecture extensions for greater impact on system performance. All Cortex-A processors are backwards compatible and backed by a strong Arm ecosystem.

Cortex-A processors offer support for a range of full Operating Systems including Linux, Android and Chrome.

Cortex-A series processors have been developed to run a number of architecture extensions:

 

Multi-core technology

All Armv7-A and Armv8-A based processor cores featured in the current Arm processor portfolio supports Arm's multi-core technologies.

  • Up to eight-core implementations for all DynamIQ based processors
  • Up to quad-core implementation for all processors using Armv7-A and the original Armv8-A specification

A number of key points are common to the Cortex-A family of devices:

  • Performance and efficiency: Scalable from single to multi-core with full hardware coherency
  • Flexibility and scalability: Build for premium, mid-range, and entry level
  • Market-leading ecosystem: Rich software and hardware ecosystem built on Arm TrustZone foundation

 

Industry standard

The success of the Cortex-A processors is built on the innovation of Arm partners who have licensed these processors and developed a wide array of success stories in various markets.

 

Cortex-A applications

Cortex-A series processors scale efficiently across a range of mobile, consumer, embedded and infrastructure devices. Cortex-A processors have shipped billions of units across markets, such as:

  • Smartphones
  • Automotive and ADAS Systems
  • Server and networking
  • Wearables
  • Tablets and readers
  • Set-top and satellite receivers
  • Home gateways
