Shahwar Masood, M. A. H. Shamshi, Syed Musthak Ahmed · 2017
In the recent days Fast Adders are implemented to increase speed, reduce delay, besides being cost effective. Several architectures and implementations of binary adders, gates, etc. were used in the past. But it was leading to complexity of the structure and also obscurity in implementation. In the proposed research paper implementation of Carry Look-ahead Adder (CLA) using Fast Adder for signal processing applications is carried out. In Optical domain this provides unmatched speed for transmission of information i.e. at the speed of light. MZI switches are used in the proposed design with reversible functionality. Two structures are presented to reduce design complexities which results in increased speed, reduced delay and hence cost effective. The results are verified using the simulation procedure carried out with programming in Verilog HDL.
