Step 1

First, we need to modify the multiplier to accept a 4-bit variable A and a constant K = 1101. We can do this by adding a 4-bit input for A and connecting the constant K to the inputs of the multiplier. Show more…

Redesign the 4-bit parallel multiplier shown in Figure 1 so it can be used to multiply a 4-bit variable A by a constant K = 1101.
