In this video, we provide a detailed explanation of the Two-Pass Assembler, covering data structures, opcode tables, and machine code generation. We also demonstrate a step-by-step example of the Two-Pass Assembler process.

🔹 What You’ll Learn:
✅ Introduction to Assemblers & Two-Pass Assembly Process
🔸 What is an Assembler, and why is the Two-Pass approach used?
🔸 Difference between One-Pass and Two-Pass Assemblers.
✅ Pass 1: Intermediate Code Generation & Symbol Table Construction
🔸 Building the Symbol Table for labels and addresses.
🔸 Literal Table & Pool Table Construction.
✅ Pass 2: Machine Code Generation
🔸 Resolving addresses using Symbol Table & Literal Table.
🔸 Generating Target (Machine) Code.
✅ Understanding Important Data Structures:
🔸 Mnemonic Opcode Table (MOT) – Stores opcode mnemonics.
🔸 Pseudo Opcode Table (POT) – Handles assembler directives.
🔸 Symbol Table (ST) – Stores labels and their memory addresses.
🔸 Literal Table (LT) – Stores constant values used in the program.
🔸 Pool Table – Tracks multiple literal pools.
✅ Step-by-Step Example Walkthrough
🔸 Analyzing Assembly Code & Generating Intermediate Code.
🔸 Building Tables & Resolving Addresses.
🔸 Generating Final Target Machine Code.
✅ Final Conclusion:
🔸 How Two-Pass Assemblers simplify code translation.
🔸 Encouragement to watch upcoming videos on Single-Pass Assemblers & Linkers.
