In this Manuscript discuss the High-performance Ripple Carry Adders (RCAs) in digital logic circuits design with uses of Addition forms the basis for many processing operations, from ALUs to address generation to multiplication to filtering. As a result, adder circuits that add two binary numbers are of great interest to digital system designers. An extensive, almost endless, assortment of adder architectures serves different speed/power/area requirements
