Question $3(3$ points$)$

Saved

A processor without structural hazards will always have a lower CPI than one with

structural hazards. However, why is it sometimes advantageous to have structural

hazards?

Hardware cost of duplicating functional units may be too high

Memory bandwidth required for separate instruction and data caches may be

too high

Hardware cost of dual ported caches may be too high

All of the above

It is never advantageous to have structural hazards
