Which of the following statements is fundamentally TRUE for a typical RISC (Reduced Instruction Set Computer) architecture?
Which of the following statements is fundamentally TRUE for a typical RISC (Reduced Instruction Set Computer) architecture?
Multiple Choice Options
- A
Heavy reliance on microprogrammed control units
- B
Instructions take variable, complex multi-cycle execution times
- C
Features very few CPU registers
- D✓ Correct Option
Strong design emphasis on optimizing instruction pipelines and hardwired single-cycle execution
Detailed Technical Solution & Explanation
RISC architectures focus on streamlining the instruction pipeline using hardwired control units, fixed 32-bit instruction formats, load/store memory operations, and single-cycle execution per stage.
Option Analysis:
•
Option A (Microprogrammed control): CISC feature; RISC uses hardwired control.
•
Option B (Variable multi-cycle): CISC feature; RISC strives for single-cycle execution.
•
Option C (Fewer registers): False; RISC has large register files (32 to 128+ registers).
•
Option D (Emphasis on optimizing pipelines): Correct; core RISC design philosophy.
