Analyze the advantages and differences between Cortex-A7 processor and Cortex-A15 processor
Cortex processors have always been very popular, and many users also like to compare their previous products. The advantages and differences between Cortex-A7 and Cortex-A15 are also enthusiastically discussed. -Analyze the respective advantages of A7 processor and Cortex-A15 processor and the difference between the two.
Regarding the ARM Cortex-A7 processor and Cortex-A15 processor, they are a family, and they are both products under the Cortex-A series. Cortex-A7 is the abbreviated version of Cortex-A8, originally designed as the companion core of Cortex-A15. Similarly, whether it is Cortex-A7 or Cortex-A15, it is developed based on the ARMv7 +MP+LPAE architecture.
In terms of performance, the Cortex-A15 processor has an absolute advantage
The Cortex-A15 MPCore processor has an unordered superscalar pipeline with a tightly coupled low-latency level 2 cache that can be up to 4MB in size. Other improvements in floating point and NEONâ„¢ media performance enable devices to provide consumers with a next-generation user experience and provide high-performance computing for web infrastructure applications.
In terms of energy consumption, Cortex-A7 processor's low power consumption is its characteristic
The power consumption and area of ​​the Cortex-A7 processor are similar to the ultra-efficient Cortex-A5, but the performance is increased by 15-20%, and it is fully compatible with the high-end Cortex-A15 CPU architecture, including large physical address extension (LPAE), hardware virtualization support And AMBA4 ACE (AMBA conformance extension). The small and energy-efficient Cortex-A7 is ideal for stand-alone CPUs in the latest low-cost smartphones and tablets, and can be combined with Cortex-A15 in the big.LITTLE processing configuration.
In 2005,our company has transferred from a single PCB manufacturer to a solutioner for PCBA and electronic products by resource integration and huge investment of SMT and X-Ray electronic examing equipment.
Our PCBA Assembly workshop has more than 300 high-quality employees, more than 4,000 square meters of production plants and all are dust-free workshops.
