In which instruction format a small number instruction required to do calculation?
Correct answer: B. One-address instruction
- A. Zero-address instruction
- B. One-address instruction
- C. Two-address instruction
- D. Three-address instruction
Explanation
One-address instruction uses one memory operand. This operand can be the source or the destination for the operation. One-address instructions are suitable for simple arithmetic and logical operations involving a value from memory and a register or another value from memory. So, option (b) is correct for small number instructions requiring one operand from memory.In conclusion, for small number instructions that require one operand from memory, a (b) one-address instruction format is the most space-efficient option
