Serial Adder Block Diagram. Serial adder if speed is not of great importance a cost effective option is to use a serial adder serial adder. In serial adders pairs of bits are added simultaneously during each clock cycle.
Bits are added a pair at a time in one clock cycle a a n 1 a n 2 a 0 b b n 1 b n 2 b 0. Block diagram of serial binary adder. A serial adder consists of a 1 bit full adder and several shift registers.
Figure 9 32 block diagram of a serial adder.
Figure show the block diagram for the serial adder let us consider a anâ 1 anâ 2â a0 and b bnâ 1 bnâ 2 â b0 are the two unsigned numbers that has to be added to produce the sum s snâ 1 sn 2â so. A block diagram of a serial adder is shown in figure 9 32. Serial adder if speed is not of great importance a cost effective option is to use a serial adder serial adder. Shift register is a group of flip flops used to store multiple bits of data.
