##### Assume a machine with a 7-stage pipeline.

Assume a machine with a 7-stage pipeline. Assume that branches are resolved in the sixth stage. Assume that 20% of instructions are branches. How many instructions of wasted work are there per branch misprediction on this machine?

Since branch are resolved at $6^{th}$ stage there will be NOP 5 cycles i.e stalls for next $5$ cycles.
