3. Assume that the following is the outcome of a particualr branch when exeucted: (a) NT, NT, NT, NT, NT, T (actual) What is the percentage of mispredition for a 2-bit preictor with initial value 11? Check FSM of 2- bit predictor**** 00-strongly not taken, 01 weakly not taken, 10- weakly taken, 11- strongly taken. (b) X0= 0 ADDI X1,X0,X0 ADDI X2, X0, X0 L2: ADDI X2, X2, (1)$_{10}$ SUBI X3, X2, (3)$_{10}$ BNE X3, X0, L2 -- Branch 0 What is the percentage of mispredition for branch 0 for a 2-bit preictor with initial value 00?

L2:
ADDI		X2, X2, (1)$_{10}$
SUBI		X3, X2, (3)$_{10}$
BNE		X3, X0, L2
-- Branch 0
What is the percentage of mispredition for branch 0 for a 2-bit preictor with initial value 00?
