Answer: Yes, RISC has better performance than CISC at present .
Explanation: Following are the reasons for the better performance of the RISC as compared to CISC:-
- RISC(Reduced instruction set computer) processors has simple instructions which take about one clock cycle whereas CSIC (complex instruction set computer) processor has complex instructions which may take multiple clocks to execute.
- Decoding of instruction in RISC is simple as compared to CISC .
- Execution time is less in RISC whereas CISC takes more time to execute
- RISC has reduced instruction that is the instructions are less but in CISC , the instruction set is complex which make the operation more complex
- No requirement of external memory in RISC for calculation but CISC requires external memory for calculation.
