Question: A 16x8 ROM has 4 address lines (A0, A1, A2, A3) and 8 data lines (D0, D1, D2, D7). Convert it into a 32x4 ROM

A 16x8 ROM has 4 address lines (A0, A1, A2, A3) and 8 data lines (D0, D1, D2, D7). Convert it into a 32x4 ROM by adding another address line A4 and using logic gates to form new data lines C0, C1, C2 and C3, such that Ci = Di for A4=0 and Ci = Di+4 for A4=1.
