Current used for "each" instruction cycle

Hi all,

I am an Engineering student and I have a little confusion.

When developing a system with Micro-Controller (for example Attiny 417) - it is assumed as a digital component which work in a digital manner, right?

1. How can I calculate or predict what current will it consume at each instruction cycle?
   
   
2. If I use a few instructions to make some "simple operation" (i.e. check memory according to incident) - will the current be "high" consumed only during the time of executing...
