What are the pros and cons of RISC and CISC?
What are the pros and cons of RISC and CISC?
RISC & CISC: Pros & Cons In terms of memory, RISC uses hardware to execute instructions with no memory references, while CISC uses many memory references to process complex instructions. In terms of execution, RISC has faster processing, while CISC has slower processing.
What is the advantage of RISC over CISC?
The performance of RISC processors is often two to four times than that of CISC processors because of simplified instruction set. This architecture uses less chip space due to reduced instruction set. This makes to place extra functions like floating point arithmetic units or memory management units on the same chip.
Why RISC is more efficient?
In very small devices, RISC is more power efficient because the extra instruction decode logic in a CISC processor has a cost. But this is true only at the very low end. This is where ARM’s initial dominance came from. But in high performance CPUs, the instruction decode logic is tiny.
What are the advantages of CISC Mcq?
Both the CISC and RISC architectures have been developed to reduce the______….
| Q. | The advantage of RISC processor over CISC processor is that |
|---|---|
| A. | the hardware architecture is simpler |
| B. | an instruction can be executed in one cycle |
| C. | less number of registers accommodate in chip |
| D. | parallel execution capabilities |
What are advantages of RISC Mcq?
Explanation: The advantages of RISC processors are that they can work at high clock frequency, can be designed, developed and tested more quickly with a high speed.
What is the main difference between CISC and RISC Mcq?
Difference –
| RISC | CISC |
|---|---|
| Requires more number of registers | Requires less number of registers |
| Code size is large | Code size is small |
| An instruction execute in a single clock cycle | Instruction takes more than one clock cycle |
| An instruction fit in one word | Instructions are larger than the size of one word |
