243 Maze Project – RISC-V on DE1-SoC FPGA

Overview

This project implements a 3D projected maze game on the DE1-SoC FPGA board, using a custom RISC-V processor architecture. The player navigates the maze using a PS/2 keyboard, and game events are enhanced with audio feedback.

Features

• ✅ 3D projected maze rendering
• ✅ RISC-V architecture implemented on FPGA
• ✅ Real-time user interaction via PS/2 keyboard
• ✅ Audio output for actions and events
• ✅ Modular and optimized for performance on DE1-SoC

Hardware Used

• DE1-SoC FPGA Board
• VGA Display (for maze rendering)
• PS/2 Keyboard (for input)
• Audio Output (3.5mm jack or onboard audio codec)

Controls

• Arrow keys: Move forward, turn left/right
• Escape: Exit game/reset
• Optional: Add key bindings for special interactions or debug mode

Architecture

• Custom RISC-V CPU: Lightweight, pipelined
• VGA Controller: For 3D maze projection
• PS/2 Controller: Decodes keyboard inputs
• Audio Module: Outputs sound on events
• Game Logic: Handles position, collisions, and rendering state

Build & Run

1. Open project in Intel Quartus Prime
2. Compile and program the FPGA
3. Connect VGA display, PS/2 keyboard, and optional speakers
4. Power on and start navigating the maze!

Future Improvements

• Add sound variety and effects
• Improve rendering with texture mapping or shading
• Add multiple maze levels or procedural generation
