How to identify the several version numbers of ARM

ARM model naming issue

●ARM7 and ARMv7 are not the same thing ●Cortex-A9 came out earlier than Cortex-A7 ●The models are very confusing. Beginners can’t tell which is which and are confused.

Several version numbers of ARM

●ARM kernel version number-ARMv7

●ARM SoC version number-Cortex-A8

●Chip model-S5PV210

Differentiation of various version numbers of ARM

As shown above:

ARM kernel version number: ARMv7

ARM’s SoC (System on Chip) version number: Cortex-A8

Chip model: S5PV210

Starting from the ARMv7 core, the ARM product line is divided into three series. This is the demand and choice of market segmentation.

Cortex series:

-M microcontroller microcontroller microcontroller

-A application application-level processor is the CPU of mobile phones, tablets, and computers

Such as Cortex-A53 A57

-R realtime The real-time processor has a relatively fast response speed and is mainly used in industry, aerospace and other fields.

Real-time operating system RTOS
