Parallel Adder With Accumulator. 6 addition creates a sum and a carry out. This is a parallel adder.
The parallel adder subtractor performs the addition operation faster as compared to serial adder subtractor. 4 bit parallel adder using full adderscontribute. This is a parallel adder.
For an n bit parallel adder it requires n computational elements fa.
The output is in parallel form i e all the bits are added subtracted at the same time. Since the accumulator will be the one outputting the values it must be 6 bit. 6 addition creates a sum and a carry out. Figure 4 shows an example of a parallel adder.
