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.
