A Crossbreed Cascaded Adder Architecture Using MATLAB Simulation
N. Balakumar · SSRN Electronic Journal · 2018
In early adder circuits the primary constraint was area, which led to development of simple scheme such as carry-skip, which improve the speed of addition while maintaining low gate-count. As technology scaling continued, several parallel prefix schemes like carries look ahead adder and Kogge stone adder are developed to yield fast adder design. The analysis of 16 bit Kogge stone adder is made designed using Weinberger and ling recurrence algorithm and the analysis based on some simulation parameters such as no of gates, power-delay product. The design of Kogge-stone adder has been carried out by using TANNER EDA tool. The efficiency of the adder design can be improved by prefix selection, algorithm, computational sum and logic depth. When Compared to Weinberger algorithm, the number of gates used is less in ling recurrence algorithm.
