Assembly Language Examples

A collection of assembly language programs for x86_64 architecture.

Programs

1. Hello World (hello.asm)

Basic program that prints "Hello, World!" to stdout.

Build:

nasm -f elf64 hello.asm
ld hello.o -o hello
./hello

2. Mandelbrot Set (mandelbrot.asm and mandelbrot_win.asm)

Generates an ASCII art representation of the Mandelbrot fractal set.

Features:

• Computes Mandelbrot set iterations for each pixel
• Maps iterations to ASCII characters for visualization
• Outputs 80x24 character grid
• Linux version: mandelbrot.asm
• Windows version: mandelbrot_win.asm

Build Linux:

nasm -f elf64 mandelbrot.asm
ld mandelbrot.o -o mandelbrot
./mandelbrot

Build Windows:

nasm -f win64 mandelbrot_win.asm
gcc mandelbrot_win.obj -o mandelbrot.exe
mandelbrot.exe

Algorithm:

• Maps screen coordinates to complex plane
• Iterates z = z² + c until |z| > 2 or max iterations
• Uses SSE instructions for floating-point calculations

Requirements

• NASM assembler
• Linux with x86_64 architecture
• GNU ld linker

Running on Windows

For Windows, you can use WSL or cross-compilation tools.
