6. Suppose you had a computer that, on average, on the programs that you run:

Instruction miss rate: 2.5%

Data miss rate: 8.0%

Percentage of memory instructions: 25%

Miss penalty: 100 cycles

NAME Sample Exam_ exhibited the following properties

There is no penalty for a cache hit (i.e. the cache can supply the data as fast as the processor can consume it). Assume also that a cache-block is one word. You are planning to upgrade the memory to one that is twice as fast. How much faster is the system with the new memory than the original system?
