1. Draw and label your own version of the memory hierarchy discussed in class.

Where are faster elements located?

How do we illustrate relative capacity?

2.Consider two machines with two different instruction sets. Machine A has a 2 GHz clock, and machine B has a 4 GHz clock. The following measurements are recorded upon execution of a program.

Machine A	Instruction Class
	Arithmetic	Load/Store	Branch
Instruction Count (millions)	10	4	6
CPI	2	3	1

Machine B	Instruction Class
	Arithmetic	Load/Store	Branch
Instruction Count (millions)	14	5	8
CPI	2	8	1

For Machine A, what is the average CPI and execution time?

For Machine B, what is the average CPI and execution time?
