So, for example, the fact that a multiply instruction is available is a computer architecture issue. How that multiply is implemented is a computer organization issue. • Architecture is those attributes visible to the programmer o Instruction set, number of bits used for data representation, I/O mechanisms, addressing techniques. o e.g.

Computer Architecture Computer Organization •The operational units and their interconnections that realize the architectural specifications •Hardware details transparent to the programmer, control signals, interfaces between the computer and peripherals, memory technology used •Instruction set, number of bits used to represent various

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.

1.1 Computer Organization and Architecture Computer Architecture refers to those attributes of a system that have a direct impact on the logical execution of a program. Examples: o the instruction set o the number of bits used to represent various data types o I/O mechanisms o memory addressing techniques
