The Cortex-A53 is a 2-wide decode superscalar processor, capable of dual-issuing some instructions . It is a low-power processor with 64-bit capabilities, applicable in a range of devices requiring high performance in power-constrained environments .
Architecture
The Cortex-A53 is an 8-stage pipelined processor with a 2-way superscalar, in-order execution pipeline . It has DSP and NEON SIMD extensions that are mandatory per core . The processor has a VFPv4 Floating Point Unit onboard (per core) and hardware virtualization support . It also has TrustZone security extensions, 64-byte cache lines, 10-entry L1 TLB, and 512-entry L2 TLB . The Cortex-A53 has 4 KiB conditional branch predictor, 256-entry indirect branch predictor.
Performance
The Cortex-A53 is the most widely used platform for mobile SoCs since 2014 to the present day [as of ], making it one of the longest-running ARM platforms for mobile devices . It is currently featured in most entry-level and lower mid-range SoCs, while higher-end SoCs used the newer ARM Cortex-A55 . The latest SoC still using the Cortex-A53 is the MediaTek Helio G36, which is an entry-level SoC designed for budget smartphones . The ARM Cortex-A53 processor has been used in the LeMaker HiKey since 2015, the Raspberry Pi 3 since February 2016, and the Raspberry Pi Zero 2 W since October 2021 . The Cortex-A53 is also used in a number of Qualcomm, Samsung, and MediaTek SoCs . Semi-custom derivatives of the Cortex-A53 have been used in Qualcomm’s Kryo 250 and Kryo 260 CPUs . The Starlink ground terminals utilize a quad-core Cortex-A53 SoC from STMicroelectronics as its main control unit . The processor is used in the ODROID-C2 and in Roku streaming media players (in the high-end models from 2016 and in all models released between 2017 and 2019) . Another notable Cortex-A53 application is the Pine A64/A64+ single-board computer. These cores are used in a 24-core SoC, the Socionext SynQuacer SC2A11 . The processor is used in Amazon Fire tablets, including the Fire HD 8 and the Fire HD 10 (the latter also includes Cortex-A72 cores) as well as the Nintendo Switch . It is also used in some Amazon Echo Show models such as the Echo Show 5, Echo Show 8, and Echo Show 5 (2nd Gen).
