Question

The number of CPIs(Clock Per Instruction) for an instruction of RISC processors is

(a) 0

(b) 1

(c) 2

(d) 3

I got this question in a dream while sleeping

Query is from Hybrid Architecture -RISC and CISC Convergence, Advantages of RISC, Design Issues of RISC Processors -2 topic in chapter RISC Architecture of Microprocessor

Answer 1

Right choice is (b) 1

The explanation: RISC processors have unity CPI(Clock Per Instruction), which is due to the optimization of each instruction on the CPU and massive pipelining embedded in a RISC processor.
