ARMv4 Assembly Tutorial (32-bit)

Welcome to the 32-bit ARMv4 Assembly Language Tutorial repository!

This tutorial is designed for those who want to understand low-level programming using real assembly code on the ARMv4 architecture. It’s hands-on, beginner-friendly, and pairs nicely with C code for comparison.

What You'll Learn

  • How to write, run, and debug assembly code for ARMv4
  • The relationship between C and assembly at the binary level
  • ARM's memory model, registers, calling conventions, and more
  • How to use tools like arm-none-eabi-gcc, as, objdump, qemu, and gdb

Tutorial Structure

Each directory covers a single concept with example code and explanations:

01_hello-assembly/           👉 Your first assembly run!
02_moving-data-around/       👉 Moving data between registers and immediates
03_doing-math/               👉 Arithmetic operations (add, sub, neg)
04_store-to-memory/          👉 Store/load data to memory
05_branching/                👉 Conditional branches and condition flags
06_comparing-values/         👉 Comparing values with CMP
07_advanced-topics/          👉 Loops, floating point, pointers, arrays, etc.

Each folder contains:

  • Assembly and/or C code files
  • A README.md with goals, explanations, and run instructions

Getting Started

Prerequisites

  • arm-none-eabi-gcc toolchain
  • qemu-system-arm and gdb-multiarch or arm-none-eabi-gdb
  • Basic understanding of C (helpful but not required)

Install on Ubuntu:

sudo apt install qemu gdb-multiarch

Who Is This For?

  • Students learning computer architecture or embedded systems
  • Developers curious about how C translates to machine code
  • Anyone who wants to really understand what’s happening under the hood

Contributing
