 		 #114602 - I doubt that would be the general case.
Responding to: ???'s previous message
As for code memory usage comparison between the 8051 and ARM - this is purely speculative- I would say about twice for the ARM
I doubt that would be the general case. If you have a lot of math on 32 bit values, I could see the ARM possibly use less code memory. I have never done "the same" on an ARM and a '51 but I once did a product where the low end models ran on a '51 and the high end models ran on a XA. Some modules compiled to less, some to more memory usage.

every comparison will be application dependent.

I am sure that, had I the time, I could write two apps one where the '51 would shine and one where the ARM would shine.

It is the old unanswerable question "which micro is the best"
