Suppose you own a computer that exhibits the following properties on the programs that you run: - the pipeline can accept a new instruction every cycle
- the cache can provide data every cycle (i. e. no penalty for cache hits)
- the instruction cache miss rate is 2.5%
- the data cache miss rate is 3.5%
- 30% of instructions are memory instructions
- the cache miss penalty is 80 cycles.

Suppose, also, that you have decided to purchase a new computer. For the budget allocated, you can either
a. purchase a machine with a processor and cache that is twice as fast as your current one (memory speed is the same as the old machine, though), or
b. purchase a machine with a processor and cache that is the same speed as your old machine but in which the cache is twice as large.

Assume, for the purposes of this problem, that the cache miss rate for the programs you run will drop by 40% with this larger cache (although this is generally not true in the real world). Which computer are you best off purchasing? Explain in detail, showing the relative performance of each choice.
