The development of processor technology has always been a topic of discussion, and now electronic products are widely available, whether it is smartphones or tablets, processors are the core of the operation of these electronic products. The ARM Cortex family of processing has always been widely used, and an analysis of the Cortex-A53 processor is carried out below.
The Cortex-A53 processor, a product of the A50 processor, marks the further expansion of ARM's leadership in high performance and low power consumption, which led to the birth of the Cortex-A53 processor. ARM Cortex-A53 is one of the first two microarchitectures to implement armv8-A 64-bit instruction sets designed by ARM Holdings. The Cortex-A53 is an oversized processor capable of issuing some instructions in double quantities.
Cortex-A53 is not only the most power efficient ARM application processor, but also the world's smallest 64-bit processor. Can operate independently or integrated into ARM big. LITTLE processor architecture. The scalability of this processor family enables ARM partners to develop system-level chips (SoCs) for a wide range of market needs, including smartphones and high-performance servers.
Cortex-A53 will continue to drive the mobile computing experience, delivering up to three times the performance of existing superphones and extending the existing superphone experience to entry-level smartphones. Complete tool suites and simulation models with ARM and ARM partners to accelerate and simplify software development, fully compatible with the existing ARM 32-bit software ecosystem, and integrate with ARM's rapidly evolving 64-bit software ecosystem.

An overview of the performance analysis and features of the Cortex-A7 processor
As described in the previous article on the characteristics of the Cortex-A7 processor, the Cortex-A7 processor was once rated as the most effective application processor ever developed by ARM, significantly extending ARM's low-power leadership in entry-level smartphones, tablets, and other advanced mobile devices. The Cortex-A7 processor is an energy-efficient ARMv7-A architecture-based processor introduced by ARM for a single-core multi-core MCU using a 28nm/40nm manufacturing process. The processor is fully compatible with programs developed by other Cortex-A-Series processors, and the Cortex-A7 processor has the same architecture and feature set as the Cortex-A15 processor, using new technologies including virtualization, large physical address extension (LPAE) NEON Advanced SIMD, and AMBA 4 ACE consistency. The Cortex-A7 processor focuses on the balance between performance and power consumption.
The difference is that the microarchitecture of the Cortex-A7 processor focuses on providing optimal energy efficiency, so both processors are available at big. Little (size core companion structure) configurations work together to provide the ultimate combination of high performance and ultra-low power consumption. A single Cortex-A7 processor is five times more energy efficient than an ARM Cortex-A8 processor, with a 50% performance improvement, compared with a fifth of the size of the latter.
Widely used in the Internet of Things, power, medical equipment, environmental testing, smart cities, smart agriculture, industrial control, human-machine interface, financial equipment, charging piles and other fields.
The Cortex-A53 emerged as a replacement for the Cortex-A7, which performed about 30% better than the Cortex-A7's web pages in a single-core test at 1.2GHz.
The Cortex-A7 processor is an energy-efficient processor based on armv7-A architecture introduced by ARM corporation and has been widely used in low-cost, full-featured entry-level smartphones since 2012. The processor is fully compatible with programs developed for other Cortex-A-Series processors and draws on the design of the high-performance Cortex-A15 processor with new technologies including virtualization, large physical address extension (LPAE) NEON Advanced SIMD, and AMBA 4 ACE consistency. The balance between performance and power consumption is also considered. A single Cortex-A7 processor with a 28nm process is five times more energy efficient than the 65nm process ARM Cortex-A8 processor, used in many popular smartphones between 2010 and 2012, with a 50 per cent performance improvement, compared with a fifth of the size of the latter. Compared to mainstream smartphones in 2011, phones with Cortex-A7 processors, launched in 2013, can deliver CPU performance gains of up to 20% and power consumption reductions of 60%. The Cortex-A7 processor also forms the big.LITTLE architecture with the Cortex A15 core. The Cortex-A7 processor has a processor frequency of at no less than 1GHz at 28nm and a single core area of 0.45mm2 with FP, NEON ™, and 32K L1 cache.
Cortex-A53 processor is based on the ARMv8 architecture, and like its high-end "brother" Cortex-A57, it is a 64-bit architecture, which is currently the main force of ARM, and the instruction set is fully compatible with both, forming a new big. LITTLE partner. The A53 is a dual-emission sequence execution architecture that is more flexible in instruction concurence than the Cortex-A7, with branch prediction, data processing, load storage, floating point/NEON, and so on all emitted simultaneously from both decoding paths. The A53's overall rendering line has not changed much, is still eight levels, can be divided into three levels of pick plus five levels of decoding execution, or seven levels of floating point / NEON. Most instructions are completed in a single cycle, so the accuracy of branch predictions is critical. Fortunately, the A53 has improved significantly in this regard, even drawing on the dual-launch disordered implementation architecture A12. The back-end section has also been improved and the data path is clearer. Basically, the A53 does the ultimate in sequential execution architecture. Even without the 64-bit model, the A53 would be much faster than the previous A5/A7, or even completely over the A9, but here are 1.2GHz, the A9r4 can be more frequent victory, the A53 can run to 2.3GHz is not easy to say. Another focus of the A53 architecture is to reduce power consumption and improve energy efficiency, with the goal of no more than 0.13W per core when running the SPECint2000 test under the 28nm HPM manufacturing process. Qualcomm uses 28nm LP, which may consume slightly more power, but is still extremely low in absolute terms.
