My understanding is that ARM Cortex-A7 architecture was released after Cortex-A9 and improves features of previous versions. However, I have only found one manufacturer, NXP, that uses Cortex-A7 architecture in their processors. I am referring to manufacturers that mass produce microprocessors only. Suggestions?
I have seen many A20's used for phones and tablets applications. I am actually working on an industrial project and they want an industrial processor for their board. Is A20 a safe option for industrial control systems?
