Why separate GUI design and real time processing?

Using one processor for both real-time and GUI functions seems less costly and conceptually simpler, but it doesn’t work out in practice. Embedded programmers are comfortable designing and implementing core functionality in application-specific microcontrollers, not in complex multi-tasking GUI hosts. In our experience, it makes sense to keep real-time and GUI code on separate processors. GUI design needs to be flexible, so you can change screen sizes, display and touch technology, and so forth without impacting proven critical-to-function embedded code. Best of all, it is far more testable!
