1. Consider the multi-cycle pipeline diagram below

Assume time for stages is 100ps for register read or write, and 200ps for other stages.

If each instruction was executed in one clock cycle (single-cycle implementation), What would be, in ps, the single-cycle execution time for the program segment above?

2. Consider the multi-cycle pipeline diagram below:

Assume time for stages is 100ps for register read or write, and 200ps for other stages.

What is, in ps, the pipeline execution time for the program segment above?
