Architecture & Organization (continued) 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? 4
5
Architecture & Organization 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 5
6
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 6
