This project presents the design and simulation of a basic 28-bit CPU architecture using Logisim, a digital circuit design and simulation tool. The CPU includes essential components such as the Arithmetic Logic Unit (ALU), control unit, registers, and supports instruction cycle simulation.
- 28-bit CPU architecture design
- Arithmetic Logic Unit (ALU) supporting basic operations
- Control Unit managing instruction cycles
- Register set for data storage and manipulation
- Instruction fetch, decode, and execute cycle simulation
- Logisim — Digital logic circuit simulator
This CPU design project aims to provide a practical understanding of computer architecture concepts by building a simplified CPU from fundamental digital components. It demonstrates:
- Digital circuit design principles
- Control and data path organization
- Instruction cycle management
- Integration of ALU, registers, and control signals
- Download and install Logisim.
- Clone or download this repository.
- Open the
.circfile in Logisim. - Simulate the CPU operation, step through instruction cycles, and observe internal signal changes.
