Enhanced 32-Bit Adder Implementation using Different Configurations of Adders

Abstract

Adders play a essential role with in the digital signal process systems. The 32-bit configuration is commonly used in few computerized systems and processors. In this paper, detail study about the implementation of 32-bit adders like Ripple Carry Adder (RCA), Carry Select adder (CSLA) and Carry Increment adder (CINA) is done for various configurational full adders using VHDL. The outcomes are acquired by executing VHDL in Xilinx ISE 14.5 with speed grade -5 of Spartan 3E family device.
