19-Bit Multi-Cycle Computer

About

This project involves the creation of a unique 19-bit Instruction Set Architecture (ISA) and a corresponding multi-cycle computer. It was designed to implement the ISA using Verilog and aimed at providing a deep understanding of how microprocessors are designed and how they function within digital systems.

Design Objectives

1. Custom ISA Development: To design a unique ISA that would support basic computational tasks and learn the principles behind instruction set architecture.
2. Real-World Application: To simulate the functionality of real-world computers using a simplified model that can be expanded or modified for educational purposes.
3. Hands-On Learning: To offer students and enthusiasts a practical experience in computer architecture and digital design.

Technical Specifications

• ISA Width: 19-bit instruction set capable of accommodating complex commands within a simplified framework.
• Address Bus: 10-bit width supporting up to 1024 unique addresses, balancing simplicity with the capability to handle significant programming tasks.
• Data Bus: 48-bit data width, allowing for robust data handling and operations.
• Registers: Utilizes a 4x48-bit register file, providing sufficient storage for intermediate calculations and operations.

Implementation Details

• Verilog Implementation: All modules were coded and simulated using Verilog, employing tools such as Xilinx ISE and Synopsys for testing and validation.
• Simulation Tasks: The system was tested using two primary programs: a basic addition operation and a loop-based summation, ensuring the functionality and correctness of the implementation.
• Module Design: Detailed design of various modules including ALU, register file, and control unit to handle multiple cycle operations effectively.
