Architecture

How Computer Operates?

A computer operates under the control of instructions stored in its own memory unit, that can accept data (input), process data arithmetically and logically, produce output from the processing, and store the results for future use.

Architecture

• The art or science of building
• A style and method of design and construction

Computer Architecture

(continued…)

• The structure of a computer that a machine language programmer must understand to write correct programs for the machine

Who is a Computer Architect?

Answer: A person who designs computers

What do we mean by “design”? (continued)

• It is a decision-making process (usually iterative), in which the basic sciences, and math and engineering sciences are applied to convert resources optimally to meet a stated objective.

Levels of Abstraction

• System Design
• Logic Design
• Circuit Design

Digital Design: Levels of Abstraction (continued)

Logic Design:  Also called gate level abstraction. We use gates and flip-flops. The behavior is less visible, while the hardware structure dominates.

Digital Design: Levels of Abstraction (continued)

Circuit Design:  Gives visibility to resistors, transistors, capacitors, and diodes.  Mask Level – this shows the silicon structure of the chip. The layout and its implementation is given in the Integrated System Design.
