Q.1. Architecture performance [10 marks]
Answer
A certain microprocessor requires either 2, 4, or 6 machine cycles to perform various operations.
⚫ (40+g+f)% require 2 machine cycles,
⚫ (30-g) % require 4 machine cycles, and
⚫ (30-f)% require 6 machine cycles.
(a) What is the average number of machine cycles per instruction for this microprocessor?
Answer
(b) What is the clock rate (machine cycles per second) required for this microprocessor to be a
"1000 MIPS" processor?
Answer
(c) Suppose that 35% of the instructions require retrieving an operand from memory which
needs an extra 8 machine cycles. What is the average number of machine cycles per
instruction, including the instructions that fetch operands from memory?
Q.2. Architecture performance [25 marks]
Consider two different implementations, M1 and M2, of the same instruction set. M1 has a clock
rate of 2 GHz and M2 has a clock rate of 3.3 GHz. There are two classes of instructions with the
following CPIs:
Class
A
CPI for M1
CPI for M2
2.f
1.g
B
5
3
C
6
4
Note that the dots in 2 fand 1.g
indicate decimal points and not
multiplication.
a) What are the peak MIPS performances for both machines?
b) Which implementation is faster, if half the instructions executed in a certain program are from
class A, while the rest are divided equally among classes B and C.
c) What speedup factor for the execution of class-A instructions would lead to 20% overall
speedup?
d) What is the maximum possible speedup that can be achieved by only improving the execution
of class-A instructions? Explain why.
e) What is the clock rate required for microprocessor M1 to be a "1000 MIPS" (not peak MIPS)
processor?

- Scenario You work for a small company that exports artisan chocolate. Although you measure your products in kilograms, you often get orders in both pounds and ounces. You have decided that rather than have to look up conversions all the time, you could use Python code to take inputs to make conversions between the different units of measurement. You will write three blocks of code. The first will convert kilograms to pounds and ounces. The second will convert pounds to kilograms and ounces. The third will convert ounces to kilograms and pounds. The conversions are as follows: 1 kilogram = 35.274 ounces 1 kilogram = 2.20462 pounds 1 pound = 0.453592 kilograms 1 pound = 16 ounces 1 ounce = 0.0283 kilograms 1 ounce = 0.0625 pounds For the purposes of this activity the template for a function has been provided.
