The Boolean variables, I4, I3, I2, I1, I0 are set by the condition code field of the conditional branch instruction b.cond target. For b.eq target the settings are I4=0, I3=0, I2=0, I1=0, I0=0. Assuming the Z flag is Z, write a Boolean expression using I4, I3, I2, I1, I0 and Z that is true if the b.eq target should be taken. Draw a circuit from the equation.

For b.ne target the settings are I4=0, I3=0, I2=0, I1=0, I0=1. Write a Boolean expression this is true if the b.ne target should be taken. Draw a circuit from the equation.
