Computer Organization
A Quick Tour for Introduction
Department of Computer Science
Southern Illinois University at Edwardsville
Fall, 2018
Dr. Hiroshi Fujinoki
INTRO/001

2. Welcome to CS 286 Computer Organization
Agenda:
• What does computer organization mean?
Two directions of growth
Growth in computer system performance
Example: Evolution of Central Processing Unit
Course Objectives
INTRO/002

3. Welcome to CS 286 Computer Organization
• What does “computer organization” mean?
A computer = a collection of hardware components
Computer performance = collection components
Effective performance = slowest component
What are we going to learn:
How is a computer system organized?
How does each component works?
INTRO/003

4. Welcome to CS 286 Computer Organization
Two directions of growth:
Hardware Growth
Larger Components
More Components
Moore’s Law
Number of components
(Doubled in 18 months)
INTRO/004

5. Welcome to CS 286 Computer Organization
Growth in computer system performance
INTRO/005

6. Intel i4004 Processor Welcome to CS 286 Computer Organization
Introduced in 1971 with 2,300 transistors
Performance: 0.06 Million Instructions/sec (MIPS)
INTRO/006

7. Pentium III Processor Welcome to CS 286 Computer Organization
Introduced in 1999 with 28 million transistors
Claimed performance: over 1,000 MIPS
INTRO/007

Welcome to CS 286 Computer Organization
Pentium III Processor Die w/ major components
INTRO/008

9. Pentium IV Processor Welcome to CS 286 Computer Organization
Introduced in 2000 with 42 million transistors
Claimed Performance: 3,000 MIPS
INTRO/009

10. Yet another type of computers: Super-Computers
Welcome to CS 286 Computer Organization
Yet another type of computers: Super-Computers
What’s the “super-computer”?
A computer which is 12,000 times faster than Pentium-4.
What’s the difference from PC?
Special purpose computing
(such as weather forecasting, seismic wave analysis)
How large is it?
It’s at least “a room”, sometimes “a building”

NEC’s Earth Simulator I
INTRO/011

12. Welcome to CS 286 Computer Organization
Two directions of growth:
More Components
Number of components keeps increasing
Larger Components (larger capacity)
Each component hold more information
Question:
- How these contribute to better performance ?
INTRO/012

13. Welcome to CS 286 Computer Organization
Course Objectives (to answer the previous question):
• Major goals:
– Identify major components in computer systems
- Understand how each component works
– Understand how they contribute to performance
– Analyze performance (theoretical and experimental)
We will find answers for the questions during this course!!

14. Welcome to CS 286 Computer Organization
Shall we start?
