This project implements a 4-bit Parallel Adder/Subtractor in Verilog using a Ripple Carry Adder (RCA) and logic gates like XOR, AND, and NOT. The design can perform both addition and subtraction based ...

This project integrates both operations into a single circuit using a control switch. Adder Functionality: Adds two single-bit numbers; Subtractor Functionality: Subtracts one-bit numbers using the ...

Abstract: In this paper, the design of a parallel self-timed adder by using transmission gate logic style was implemented for multi bit binary addition. Parallel Asynchronous Self Timed Adder (PASTA) ...

Abstract: Dedicated hardware for decimal floating point arithmetic is becoming a necessity in commercial and financial applications which demand high speed decimal computation. Multi-operand decimal ...

Parallel prefix adder is the most flexible and widely used for binary addition. Parallel prefix adders are best suited for VLSI implementation. Numbers of ...
