Problem $2(20$ points$)$

Based on the figures of ALU above, if $A_{7\text{:}0}=01110110$ and $B_{7\text{:}0}=10010011,$ determine the four flag bits NZCV for:

a$.$ ALUControl $1$:$0=00$

b$.$ ALUControl $1$:$0=01$

c$.$ ALUControl ${?}_{1\text{:}0}=10$

d$.$ ALUControl ${?}_{1\text{:}0}=11$

Each part will be scored out of $5$ points: each flag bit is worth one point, with one 'free' point.
