Feb 9, 2021 · In this post we will create an Arithmetic & Logic Unit (ALU) using logic gates. The ALU is one of the main component of the CPU. It is used in the Execution stage of the FDE …

The ALU that will be discussed here will only be able to perform addition and subtraction on 8-bit numbers and will be built from 74HC logic using XOR, AND, and OR gates. All of which will be …

This project goal is to build a basic 8-bits computer with a functional 8-bits processor using a digital circuit simulator (LogiSim). For future versions I will expand the circuits modules and …

By setting that property to 8, you get a gate that can be connected to 8-bit inputs and outputs. In effect, an OR gate with 8 data bits is made up internally of 8 one-bit OR gates. So, you can …

Jul 1, 2020 · Building an 8-bit computer in Logisim (Part 2— Arithmetic) In this part, we will be covering how to do all the standard arithmetic operations, addition, subtraction, multiplication, …

This article outlines the process of constructing an 8-bit computer's Arithmetic Logic Unit (ALU) using Logisim, detailing the creation of a basic ALU capable of addition, subtraction, and …

An 8-bit ALU (Arithmetic Logic Unit) circuit diagram is a complex arrangement of components that are responsible for performing arithmetic and logical operations on 8-bit binary numbers. …

The AND, OR, NAND, and NOT gates each compute the respective function of the inputs, and emit the result on the output. The two-input truth table for the gates is the following.

This project is my design of a basic ALU that can perform addition, subtraction, and bitwise logic operations. This project was designed in Logisim Evolution purely through the use of digital …

I built a programmable 8-bit computer from scratch on breadboards using only simple logic gates. I documented the whole project in a series of YouTube videos and on this web site. Watch this …
