Jewel of Orion

Jewel of Orion is a vertical-scrolling space shooter released in 2005, where players navigate a spacecraft through levels, destroying moons and aliens to score points. The game features simple controls, progressive firepower upgrades, and a challenge to survive ten levels while managing three lives.

Key Chapters & Topics

1. Introduction

   • Digital system examples (computers, smartphones, medical devices).
   • Design methodologies: Top-down vs. bottom-up approaches.
   • Metrics: Area, power, performance, and testability.

2. Basics of Digital Circuits

   • Digital Abstraction: Translating physical signals into binary values (0/1).
   • CMOS Technology:
     • NMOS/PMOS transistors, logic gates (NOT, NAND, NOR).
     • Voltage levels, noise margins, and propagation delays.
   • Basic Gates: Properties of combinational gates (e.g., fan-in, fan-out).

3. Combinational Logic Design

   • Boolean Algebra: Laws, theorems, and simplification techniques.
   • Karnaugh Maps (K-maps): Minimization of Boolean expressions.
