basic-computer-logic-simulation

This is a simple computer logic simulation. It includes the basic components of a computer architecture, such as logic gates, adders, registers, and more.

All the components are implemented using Python classes and generalized to any bit size architecture.

How to run

python3 main.py

Note: The main file simply presents some examples of the implemented components. Feel free to modify it as a playground.

Vulgarization

The main components of a computer architecture are:

• Processor (CPU)
• Memory
• Input/Output (I/O)

This project focuses on the Processor part, which is the brain of the computer. It is composed of several components, such as:

• Registers
• Arithmetic Logic Unit (ALU)
• Control Unit (CU) => Not implemented in this project

The Registers are the memory units of the processor. They are used to store data temporarily during the execution of a program. In this project, the value of a register is represented by a string of bits (e.g., "10101010" for an 8-bit register).

The Arithmetic Logic Unit (ALU) is the part of the processor that performs arithmetic and logical operations. It is composed of several components, such as:

• Logic gates
• Adders
• Multiplexers
• Demultiplexers
• Shifters
• Comparators
• ...
