Chapter 1 Introduction

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?

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

Function

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

Operations (1) Data movement

Operations (2) Storage

Operation (4) Processing from storage to I/O
