1. A computer will have a multiply instruction

2. Multiply instruction will be implemented by a special multiply unit.

Which of the following is correct?

1. Both 1 and 2 are not architectural design issues
2. Both 1 and 2 are not organizational issues
3. 1 is an architectural design issue while 2 is an organizational issue.
4. 1 is an organizational issue while 2 is an architectural design issue.

Answer 1

Correct Answer - Option 3 : 1 is an architectural design issue while 2 is an organizational issue.

• Computer architecture refers to those attributes of a system visible to a programmer, or those attributes that have a direct impact on the logical execution of a program.
• As an example, it is an architectural design issue whether a computer will have a multiply instruction.
• Computer organization refers to the operational units and their interconnections that realize the architecture specification.
• An example, it is an organization issue whether the instruction (multiply instruction) will be implanted by a special multiply unit, or by a mechanism that makes repeated use of the add unit of the system
