Which of the following is a design criterion for instruction formats?
- A.
The size of instructions
- B.
The number of bits in the address fields
- C.
The sufficient space in the instruction format to express all the operations desired
- D.
All of these
Attempted by 208 students.
Show answer & explanation
Correct answer: D
Instruction format design involves several key criteria. Instruction size affects memory usage and fetch efficiency (Option A). The number of address field bits determines the maximum addressing capability (Option B). Sufficient opcode space is needed to express all required operations (Option C). Since all three are fundamental design criteria, the correct answer is All of these.
