This project implements a BCD (Binary-Coded Decimal) Adder and Subtractor using Verilog HDL, along with output display logic for 7-segment displays. It includes modules for addition, subtraction, ...

Micro-electronic devices are playing a very prominent role in electronic equipment’s which are used in daily life. For electronic equipment battery life is important. So, in order to reduce the power ...

Abstract: In this paper, we present a performance comparison of Binary Coded Decimal (BCD) Adders on Field Programmable Gate Logic (FPGA) for functional and behavioural verification. Although it does ...

4-bit Adder using ICs 🔢 4-Bit Adder Using Logic ICs This 4-bit binary adder is a modular digital circuit designed to perform addition of two 4-bit binary numbers. Built entirely from fundamental ...

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 ...

When anyone is first introduced to the topic of digital computers, they are almost invariably told that these machines are based on binary (base-2) logic and the binary number system, where “binary” ...

Abstract: In this paper, we designed a 16-bit BCD adder using power gating design, dual threshold voltage (DVT) and LECTOR technique. To achieve high density, low power and high performance device ...

My last column introduced the concepts underlying BCD (binary-coded-decimal) representations. In particular, we considered unsigned versus 10s-complement versions of BCD numbers. In this column we are ...
