The Cortex-A57 high-performance processor is designed for a wide-range of applications which require high performance, with the advantages of the Arm power-efficient architecture.
Industrial and military aerospace
Networking and base station
64-Bit Out-of-Order Pipeline
Arm’s first Armv8-A 64-bit triple-issue out-of-order pipeline which removes code dependencies to achieve high peak and sustained instruction throughputs.
3X better memory streaming performance over Cortex-A15 with improvements in the speculative prefetching features.
3-10X performance improvement on software-based cryptography applications with the introduction of the Crypto acceleration unit.
Support for networking and storage application with full ECC cache and 44-bit addressing up to 16TB.
The Cortex-A57 processor achieves high levels of performance through a range of microarchitectural implementations and an updated version of the Arm architecture. On the microarchitectural side, the processor features a highly out-of-order, multi-issue pipeline tuned for modern workloads with DSP and NEON SIMD extensions mandatory with each core. The inclusion of cryptography extensions improves performance on cryptography algorithms by 10 times over the current generation of processors. It delivers significantly more performance than the Cortex-A15, at a higher level of power efficiency.
The Cortex-A57 processor utilizes the Armv8-A architecture, enabling power-efficient 64-bit support while maintaining compatibility with existing 32-bit software. As such, the architecture can run in two states. The AArch32 execution state runs existing Arm 32-bit applications while the AArch64 state executes applications in 64-bit code. The ability to provide 64-bit support significantly raises the performance level of the processor, and is ensuring that Arm continues to provide for next-generation devices requiring the right balance of power and performance.
The Cortex-A57 processor can be incorporated into a SoC using a broad range of Arm technology including Graphics IP, System IP, and Physical IP. The Cortex-A57 processor is fully supported by Arm development tools. Related IP includes:
