The ARM Cortex-A7 processor is the most efficient ARMv7-A processor.


The Cortex-A7 processor provides up to 20% more single thread performance than the Cortex-A5 and 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.

Key benefits

  • ARMv7-A architectural extensions (40-bit physical addressing, hardware virtualization support).

  • More than 20% improvement in single thread integer performance when compared to Cortex-A5.

  • Integrated L2 cache subsystem provides improved area efficiency and up to 43% improvements in memory streaming performance.

  • Proven successful design, suited to the needs of wearable mobile devices and other UI-based consumer products.

Key features

In-order 8 stage pipeline

Improved dual issue, branch prediction and memory system performance. It features 64-bit load-store path, 128-bit AMBA 4 AXI buses and increased TLB size (256 entry).

Integrated, Configurable Size Level 2 Cache Controller

Provides low-latency and high-bandwidth access to up to 1MB of cached memory in high-frequency designs, or designs needing to reduce the power consumption associated with off-chip memory access. The L2 cache is optional on Cortex-A7.

Support ARMv7-A extensions

Hardware Virtualization and Large Physical Address Extensions (LPAE) enables the processor to access up to 1TB of memory.

big.LITTLE technology

First LITTLE processor architecturally compatible with compatible with Cortex-A15 and Cortex-A17 for various big.LITTLE processor combinations.


The Cortex-A7 processor builds on the energy-efficient 8-stage pipeline of the Cortex-A5 processor. It also benefits from an integrated L2 cache designed for low-power, with lower transaction latencies and improved OS support for cache maintenance. On top of this there is improved branch prediction and an improved memory system performance, with 64-bit load-store path, 128-bit AMBA 4 AXI buses and increased TLB size (256 entry, up from 128 entry for Cortex-A9 and Cortex-A5), increasing performance for large workloads such as web browsing.

In a 28nm process, the Cortex-A7 can run at 1.2-1.6GHz, has an area of 0.45mm2 (with Floating-Point Unit, NEON and a 32KB L1 cache) and requires less than 100mW of total power in typical conditions. This lowest performance profile makes it an ideal standalone processor for a range of mobile devices, and means the Cortex-A7 can ultimately deliver similar performance to the Cortex-A9 processor at much higher levels of power efficiency.
