what is difference between Arm7 and Arm cortex-m series??
It looks strange, because I would expect phones and tablets to contain a Cortex-A these days.
It's easy to be misguided by the statistics, to believe that the Cortex-M go into phones.
There are Cortex-A chips, which embeds Cortex-M; do you know if these count as both Cortex-A and Cortex-M?
