The number of CPIs(Clock Per Instruction) for an instruction of RISC processors is
A. 0
B. 1
C. 2
D. 3
Answer:A
The number of CPIs(Clock Per Instruction) for an instruction of RISC processors is
A. 0 B. 1 C. 2 D. 3
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.
