Abstract

This paper presents FPGA-based design of hybrid adder with the optimal bit-width configuration(out of alarge number of possible configurations) of each of the sub-adders constitute the proposed hybrid adder using a high level automated methodology. Algebraicoptimization model for the hybrid adderis built to produce the best choice of types and bit-widths of the sub-adders. In context of this work, several classes of parallel adders are designed and its performance is evaluated to serve as sub-adders inside the hybrid adder. The results show that the proposed model gains a high flexibility in allowing design tradeoffs between the performance criteria delay and areaand successfully to generate the optimalbit-width configurations of the hybrid adder.
