Cortex-A53 Processor Image (View Larger Cortex-A53 Processor Image)

The ARM ARMv8-A Cortex-A53 processor offers a balance between performance and power-efficiency and is capable of seamlessly supporting 32-bit and 64-bit code.

It makes use of a highly efficient 8-stage in-order pipeline balanced with advanced fetch and data access techniques for performance. It fits in a power and area footprint suitable for entry-level smartphones, and is at the same time capable of delivering high-aggregate performance in scalable enterprise systems via high core density.

The Cortex-A53 delivers significantly higher performance than the highly successful Cortex-A7, and is capable of deployment as a standalone applications processor or paired with the Cortex-A57 processor in a big.LITTLE™ configuration for optimum performance, scalability and energy efficiency. It is supported by a range of optimized IP targeted at designing the most efficient complete ARM-based SoCs. ARM Mali™ processors support all graphics, video and display demands, ARM POP™ IP solutions deliver an accelerated time-to-market, and optimized System IP provides the interconnect and peripheral components.




The Cortex-A53 delivers 64-bit capability and significantly increases performance over Cortex-A7, in a footprint suited for cost-sensitive applications. It is smaller and lower power than the Cortex-A9 processor and delivers more performance on key benchmarks. This means it can enable devices with the compute power of today’s high-end smartphone in the lowest power and area footprint.


As well as running 64-bit applications, the Cortex-A53 seamlessly and efficiently runs legacy ARM 32-bit applications. It is highly scalable, from a single multi-core CPU cluster, to a dual-cluster big.LITTLE CPU subsystem in combination with the Cortex-A57, to a multi-cluster enterprise system connected through AMBA® 5 CHI Coherent Interconnect technology. Full ARMv8-A support in a small and highly configurable package means that the Cortex-A53 is highly suited to a broad range of mobile, consumer, general purpose, and enterprise applications.


It features coherent interoperability with ARM Mali family graphics processing units (GPUs) for GPU compute applications, and connects seamlessly to AMBA interconnect for 16-core and 32-core configurations, delivering programmability with the most aggregate performance per Watt to high-performance enterprise applications by maximizing core count in a thermally constrained rack.




Built as a low-power processor with 64-bit capabilities, the Cortex-A53 processor is applicable in a range of devices requiring high performance in power-constrained environments.
