A smartwatch is a very useful device developed by several companies these days including Apple, Samsung, Motorola and several others. It has a touch screen interface providing features like GPS tracking, heart rate and sleep monitoring etc. with power efficient batteries. The ARM Cortex processors are used in smartwatches providing several benefits.

Suppose we have to choose between ARM Cortex-A or Cortex-M series architecture for our next generation smartwatch. Which one would you select between the two and why? Support your selection of either architecture with solid reasoning considering memory management, cost, performance and chip size.
