- 1. William Stallings Computer Organization and Architecture 8th Edition Chapter 1 Introduction
- 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
- 7. Operations (a) Data movement
- 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
