3. What is Architecture
• A high-level model of a thing
• Describes critical aspects of the thing
• Understandable to many stakeholders
• Allows evaluation of the thing’s properties before it is built
• Provides well understood tools and techniques for
constructing the thing from its blueprint

5. Architectural Design
• Establishing the overall structure of a computer system
• To introduce architectural design and to discuss its
importance
• To explain why multiple models are required to
document a computer architecture
• To describe types of architectural model that may be
used

6. Design Methodology
• System Design:
• A computer is an example of a system, which is defined informally as a
collection – often a large and complex one – of objects called components,
that are connected to form a coherent (consistent) entity with a specific
function or purpose. The function of the system is determined by the
functions of its components and how the components are connected.

7. Design Methodology
• Design Process: Given a system’s structure, the task of determining
its function or behavior is termed analysis. The converse problem
of determining a system structure that exhibits a given behavior is
design or synthesis.

9. Design Methodology
Design levels:
The processor level, also called the architecture, behavior,
or system level
The register level, also called the register-transfer level
(RTL).
The gate level, also called the logic level
