ARM offers two main families: Cortex-M (microcontrollers) and Cortex-A (application processors). The wrong choice can lead to overengineered solutions, unnecessary complexity, or insufficient performance. This guide explains the differences between Cortex-M and Cortex-A, when to use each, and how to make the right architectural decision for your project.
