  • 1. William Stallings Computer Organization and Architecture 7 th Edition Chapter 1 Introduction
  • 2. Architecture & Organization 1 <ul><li>Architecture is those attributes visible to the programmer </li></ul><ul><ul><li>Instruction set, number of bits used for data representation, I/O mechanisms, addressing techniques. </li></ul></ul><ul><ul><li>e.g. Is there a multiply instruction? </li></ul></ul><ul><li>Organization is how features are implemented </li></ul><ul><ul><li>Control signals, interfaces, memory technology. </li></ul></ul><ul><ul><li>e.g. Is there a hardware multiply unit or is it done by repeated addition? </li></ul></ul>
  • 3. Architecture & Organization 2 <ul><li>All Intel x86 family share the same basic architecture </li></ul><ul><li>The IBM System/370 family share the same basic architecture </li></ul><ul><li>This gives code compatibility </li></ul><ul><ul><li>At least backwards </li></ul></ul><ul><li>Organization differs between different versions </li></ul>
  • 4. Structure & Function <ul><li>Structure is the way in which components relate to each other </li></ul><ul><li>Function is the operation of individual components as part of the structure </li></ul>
  • 5. Function <ul><li>All computer functions are: </li></ul><ul><ul><li>Data processing </li></ul></ul><ul><ul><li>Data storage </li></ul></ul><ul><ul><li>Data movement </li></ul></ul><ul><ul><li>Control </li></ul></ul>
  • 6. Functional View
  • 7. Operations (a) Data movement
  • 8. Operations (b) Storage
  • 9. Operation (c) Processing from/to storage
  • 10. Operation (d) Processing from storage to I/O
  • 11. Structure - Top Level Computer Main Memory Input Output Systems Interconnection Peripherals Communication lines Central Processing Unit Computer
  • 12. Structure - The CPU Computer Arithmetic and Login Unit Control Unit Internal CPU Interconnection Registers CPU I/O Memory System Bus CPU
  • 13. Structure - The Control Unit CPU Control Memory Control Unit Registers and Decoders Sequencing Login Control Unit ALU Registers Internal Bus Control Unit
