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?
NXP i.MX 6UL/6ULL ARM Cortex-A7 processor is very popular at present. We are using MYIR's MYD-Y6ULX board which includes an i.MX6ul/6ull based SOM.
