16. Use 2-bits prediction scheme and determine accuracy rate by starting from WEAKLY NOT TAKEN condition if L1 loop is taken 10 times. REFER L1: R1=0 R2=99 L2: BEQ R1,R2, L1 **** ADD R1, R1,1 JUMP L2 **** Predict Tak 11 Predict Not 01 Taken NT NT NT T 10 NT Saturated states Predict Taken a) 985/1000 b) 990/1000 c) 995/1000 d) 980/1000 e) 998/1000 f) 997/1000
