![]() ![]() We explain half and full adders in detail here. Hence the resulting circuit will contain nine AND gates, three half adders, and three full adders. Thus, two carries are generated and are carried over to the addition between A2B1 and A1B2, where two more carries are created similarly. Multiplying the two numbers with each other using standard binary arithmetic rules, we get the following equation.Īdding A2B0 and A1B1 will give rise to one carry, adding the sum obtained from that, and the carry obtained from adding A1B0 and A0B1 to A0B2 will give rise to another carry. How to design a 3-bit multiplier?Ĭonsider two general 3-bit binary numbers A2A1A0 and B2B1B0. If you would like to brush up your knowledge of digital logic gates, we’ve got you covered fam. Hence the circuit obtained is as follows. The AND gates will perform the multiplication, and the half adders will add the partial product terms. Based on the above equation, we can see that we need four AND gates and two half adders to design the combinational circuit for the multiplier.
