William Stallings Computer Organization and
Architecture6th Edition

• Chapter 1Introduction

2
Architecture Organization 1

• Architecture is those attributes visible to the
  programmer
• Instruction set, number of bits used for data
  representation, I/O mechanisms, addressing
  techniques.
• e.g. Is there a multiply instruction?
• Organization is how features are implemented
• Control signals, interfaces, memory technology.
• e.g. Is there a hardware multiply unit or is it
  done by repeated addition?

3
Architecture Organization 2

• All Intel x86 family share the same basic
  architecture
• The IBM System/370 family share the same basic
  architecture
• This gives code compatibility
• At least backwards
• Organization differs between different versions

4
Structure Function

• Structure is the way in which components relate
  to each other
• Function is the operation of individual
  components as part of the structure

5
Function

• All computer functions are
• Data processing
• Data storage
• Data movement
• Control
