SIC/XE Assembler

A compact two-pass SIC/XE assembler written in C++.

This project was developed as part of my MSc coursework in Systems Programming. It reads SIC/XE assembly source, builds a symbol table in pass 1, generates object code in pass 2, and writes an object program using H, T, M, and E records.

What It Does

• Parses SIC/XE assembly input
• Builds a hash-based symbol table
• Supports format 1, 2, 3, and 4 instructions
• Handles directives such as START, END, BASE, NOBASE, WORD, BYTE, RESW, and RESB
• Produces an object file as output.obj

Files

• assembler.cpp - assembler implementation
• input.asm - sample input program
• Makefile - build and run commands

Build And Run

make
./assembler input.asm

Or use:

make run

The generated object program is written to output.obj.
