Interfacing NASM with Higher-Level Languages

Bridging Assembly and Other Languages

Sometimes, high-level languages like C or Python need to run super-fast code. You can write that code in NASM and call it from these languages.

Steps to Interface

  • Write the performance-critical part in NASM.
  • Compile and link the object file with your main program.
  • Use language-specific features (like extern in C) to call assembly routines.

Real-World Use

This is common in:

  • Cryptography libraries
  • Game engines
  • Video processing software

Examples

  • Calling a NASM-optimized math function from a C program.

  • Accelerating image processing in Python with assembly routines.
