Cortex-A7プロセッサ

The ARM® Cortex®-A7 is the most efficient ARMv7-A processor and the most successful – it has shipped over a billion units in production. The Cortex-A7 is a 32-bit applications processor with 40-bit physical addressing and hardware virtualisation support. It features an optional integrated L2 cache that can be configured from 128KB to 1MB. The Cortex-A7 pipeline is based on an eight stage in-order design that provides significant performance improvements compared to the Cortex-A5 processor.

The Cortex-A7 is architecturally compatible with the high-performance Cortex-A15 and Cortex-A17 processors and has shipped in millions of smartphones and tablets as a LITTLE processor in ARM big.LITTLE configuration and also as a standalone multicore processor cluster. The Cortex-A7 is also widely shipped in other markets like wearable devices running rich operating systems, consumer embedded devices and Single Board Computers (SBCs).

big.LITTLE
This processor can also be implemented in an ARM big.LITTLE configuration with the Cortex-A15 and Cortex-A17 processors.


Key Benefits

  • ARMv7-A architectural extensions (40-bit physical addressing, hardware virtualization support)
  • More than 20% improvement in single thread integer performance compared to Cortex-A5
  • Integrated L2 cache subsystem provides improved area efficiency and up to 43% improvements in memory streaming performance
  • Proven successful design, now well matched to the needs of wearable mobile devices and other UI-based consumer products

Applications

The Cortex-A7 is designed for use in a wide range of devices with differing requirements, particularly rich UI based wearables, which demand a balance between power and performance.
