How big of a number is 64bit? Quite big as it turns out:

Going over the bus size

Let’s do the experiment of doing calculations bigger than the bus size of a modern microcontroller and see how bad the generated assembly code look.

Does doubling the number of bits of a microcontroller double its processing power? What does it mean this number of bits?
