An Improved Optimization Techniques for Parallel Prefix Adder using FPGA
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 5
Abstract
In this paper, Carry Tree Adders are Proposed. Parallel prefix adders have the best performance in VLSI Design. Parallel prefix adders gives the best performance compared to the Ripple Carry Adder (RCA) and Carry Skip Adder (CSA). Here Delay measurements are done for Kogge-Stone Adder, Sparse Kogge-Stone Adder and Spanning Tree Adder. Speed of Kogge-Stone adder and Sparse Kogge-Stone adder have improved compared to the Ripple Carry Adder (RCA) and Carry Skip Adder (CSA). Model Simulator-Altera 6.6d and Xilinx 10.1 tools were used for simulation and synthesis of the design.
