Exercise 1. [6 Marks] Define the processor-memory gap. How have computer architec- tures changed to combat this gap? What metric looks to be minimized by these changes? Be specific with this metric; of course minimizing one metric might also decrease another, higher-level metric. Exercise 1. [6 Marks] Define the processor-memory gap.
