متن کاملDesign of Reversible Carry Skip Adder for Digital and Optical Circuits
In this paper, high speed carry skip adders for two different circuits were proposed. In the conventional structure of CSKA consists of a chain of ripple carry adder (RCA) block and 2:1 multiplexer. In the proposed structure, parallel prefix adder network is used to improve the speed and energy parameters. In addition to this the proposed structure called AND-OR-Invert (AOI) and OR-ANDInvert (O...

متن کاملHigh Performance Carry Skip Adder Implementing Using Verilog-HDL
In this paper, we present a carry skip adder (CSKA) structure that has a higher speed yet lower energy consumption compared with the conventional one. The speed enhancement is achieved by applying concatenation and incrementation schemes to improve the efficiency of the conventional CSKA (Conv-CSKA) structure. In addition, instead of utilizing multiplexer logic, the proposed structure makes use...
