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.
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
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
Functional View :
 |
Operations (a) Data movement :
 |
Operations (b) Storage :
Operation (c) Processing from/to
storage :
Operation (d) Processing from storage to I/O :
Structure - Top Level :
Structure - The CPU :
Structure - The Control Unit :
