WebThus realizing an efficient adder is required for better performance of an ALU and therefore the processor. Research started in late 1950s on designing efficient adder algorithms and their hardware implementation. Many designs based on serial and parallel structures have been proposed to optimize different parameters from time to time. WebFig 2 – Ripple carry adder Stages. In 4 bit adder, the time delay for a valid output is the sum of time delay of 4 full adders, if there is an ‘n’ bit adder, than the time delay will be the sum of time delay of ‘n’ full adders. It means, higher the bit size of the numbers, the late the answer we will get.So it is not an efficient design for complex and fast working systems.
