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 ...

Abstract: The article describes in detail the design of a 4-bit adder and subtractor. We will design the necessary sub-blocks for its proper functioning, such as a 2-bit multiplexer and a complete ...

Would you consider this to be doing math the old-fashioned way? Instead of going with silicon-based switching (ie: transistors) this 4-bit adder uses mechanical relays. We like it for its mess of ...

Abstract: In this paper, the low power and reduce Ground Bounce noise 4 bit adder has been proposed. Full adder is the most important basic building block of digital circuits employing arithmetic ...
