The ARM Cortex-A7 processor is the most power-efficient multi-core processor.

The Cortex-A7 powers sub-$100 entry-level smartphones, as well as a number of high-end wearable devices. The processor led the multicore revolution for entry-level and mid-range mobile smartphones, and devices based on the quad- and octa-core configurations are shipping in huge volumes. The Cortex-A7 processor is architecturally aligned with the high-performance Cortex-A17 and Cortex-A15 processors, enabling devices based on big.LITTLE™ technology.

The Cortex-A7 processor is supported by a suite of optimized IP targeted at mid-range solutions, bringing highest efficiency levels and ease of integration. All of our Mali™ mid-range and high-end graphics processors can be integrated with the Cortex-A7, as well as the Mali-V500 video processor and Mali-DP500 display processor. Our pervasive range of physical and system IP is also available as standard.

Overview

 

The Cortex-A7 processor is a very energy-efficient applications processor designed to provide rich performance in entry-level to mid-range smartphones, high-end wearables, and other low-power embedded and consumer applications. It provides up to 20% more single thread performance than the Cortex-A5 and provides similar performance to mainstream Cortex-A9 based smartphones in 2012 while consuming less power. It has been licensed by many of the industry’s leading silicon manufacturers including Broadcom, Freescale, HiSilicon, LG, Samsung, Texas Instruments, and many others.

 

The Cortex-A7 incorporates all features of the high-performance Cortex-A15 and Cortex-A17 processors, including virtualization support in hardware, Large Physical Address Extensions (LPAE), NEON™, and 128-bit AMBA® 4 AXI bus interface.

 

The Cortex-A7 processor is widely used as an energy-efficient LITTLE CPU with a high-performance Cortex-A15 or Cortex-A17 processor to enable ARM big.LITTLE processing. The LITTLE Cortex-A7 processor runs low processing intensity tasks such as scrolling through the contents of a web page, texting, emailing and playing audio, while the big processor (Cortex-A15 or Cortex-A17) manages periods of high processing intensity tasks such as initial web page rendering and game physics calculation. This reduces overall energy consumption and improves processing performance while extending battery life. The software can run seamlessly on the Cortex-A7 and on both the Cortex-A15 and Cortex-A17 processors as needed without recompilation.

 

Applications

 

The Cortex-A7 is designed for use in a wide range of devices with differing requirements, from high-end wearables which demand a balance between power and performance, to high-end smartphones which can make use of a big.LITTLE configuration.

 

Key target markets include:

  • High-end smartphones
  • Tablets
  • Internet of Things (IoT)
  • Advanced wearable devices
  • Routers
  • Network infrastructure
