Suppose that you design an architecture with the following characteristics: Cost of a non-branch instruction 1 cycle Fraction of instructions that are branches 20% Fraction of branches that are taken 85% Fraction of delay slots that can be filled 50% Cost of an unfilled delay slot 1 cycle For this architecture, calculate the number of cycles per instruction. 1.00 1.085 1.25 1.32

Solution

From the question :

Cycles per insructions = (20%*1+85%*1+50%*1) / 2

Cycles per insructions =1.25

Option 3 is correct choice.
