Key features

32-bit ARMv8-A architecture

The Cortex-A32 processor supports the AArch32 execution state specified in the ARMv8-A architecture profile.  In this execution state, it supports the A32/T32 instruction set and is fully compatible with ARMv7-A.

New idle power management features

Incorporates new power management features compared to the Cortex-A7 processor thereby providing more capabilities to reduce leakage power in the CPU idle states.

Scalable and versatile

The Cortex-A32 processor can be configured from a single core configuration to a maximum configuration that includes four CPU cores in a cluster with a shared L2 cache.


The Cortex-A32 processor delivers higher efficiency (performance per mW) and higher performance than the Cortex-A7 and Cortex-A5 processors.

The graph depicts relative performance improvements delivered by the Cortex-A32 processor compared to the Cortex-A5 and Cortex-A7 processors across some of the popular benchmarks. The performance comparisons are for the same clock frequency and same processor configurations.
