Open Source Assembly Libraries for Mac

libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, NEON, AltiVec) to accelerate baseline JPEG compression and decompression on x86, x86-64, ARM, and PowerPC systems. On such systems, libjpeg-turbo is generally 2-6x as fast as libjpeg, all else being equal. On other types of systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines. In many cases, the performance of libjpeg-turbo rivals that of proprietary high-speed JPEG codecs. libjpeg-turbo implements both the traditional libjpeg API as well as the less powerful but more straightforward TurboJPEG API. libjpeg-turbo also features colorspace extensions that allow it to compress from/decompress to 32-bit and big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java interface.

Mikmod is a module player and library supporting many formats, including mod, s3m, it, and xm. Originally a player for MS-DOS, MikMod has been ported to other platforms, such as Unix, Macintosh, BeOS, and Java(!!)

Apollo-11 hosts the original Apollo 11 Guidance Computer (AGC) source code for the Command Module and Lunar Module, faithfully transcribed from historical listings. It is written in AGC assembly and reflects 1960s software engineering practices, complete with comments from the original programmers. The code is both a cultural artifact and a technical reference, illustrating how limited memory and processor constraints shaped algorithms and system design. Developers can examine navigation routines, guidance logic, and task scheduling in an environment with no luxury features—everything is explicit and resource-aware. The repository’s structure and documentation make it approachable for modern readers despite the archaic environment. It’s frequently used in education, talks, and explorations of software history to show how a landmark mission depended on disciplined code and verification.

XNNPACK is a highly optimized, low-level neural network inference library developed by Google for accelerating deep learning workloads across a variety of hardware architectures, including ARM, x86, WebAssembly, and RISC-V. Rather than serving as a standalone ML framework, XNNPACK provides high-performance computational primitives—such as convolutions, pooling, activation functions, and arithmetic operations—that are integrated into higher-level frameworks like TensorFlow Lite, PyTorch Mobile, ONNX Runtime, TensorFlow.js, and MediaPipe. The library is written in C/C++ and designed for maximum portability, efficiency, and performance, leveraging platform-specific instruction sets (e.g., NEON, AVX, SIMD) for optimized execution. It supports NHWC tensor layouts and allows flexible striding along the channel dimension to efficiently handle channel-split and concatenation operations without additional cost.

This project is a partial overhaul of the Arduino hardware library, i.e. the main source files that make the core library. The intent is to reduce the overhead introduced by the initial library and eliminate the numerous function calls whenever direct register access is possible.

Project Asmosis provides a set of tools related to assembly language programming. The tools include: - the Asm::X86 Perl module, - AsmDoc - an HTML documentation generator for assembly language, - Asm4Doxy - Assembly converter for Doxygen (http://www.doxygen.org/), - converters between various assembly language dialects: NASM (The Netwide Assembler, https://www.nasm.us), fasm (flat assembler, https://flatassembler.net) and GNU as, - converters from C/C++ header files to assembly language header files, - make4fasm - a Makefile generator for fasm, - Linux-2.6 kernel module helpers for fasm and NASM, - macros for Autoconf (https://www.gnu.org/software/autoconf/), - pieces of code that may be useful for starting developing a simple operating system. See the project homepage https://asmosis.sourceforge.io and the project Wiki in the menu above.

A C++ header library for fast operations on vectors/matrices (3D/3x3) using Streaming SIMD Extensions (SSE, SSE2, SSE3, SSE4); Tends to be used in 3D graphics applications and game developement.

A cross-platform 3D rendering libarary.

This STL-like C++ library contains classes for long integer numbers processing with using of assembler functions as a backend. Lazy evaluation is also used for optimization. It also contains generic implementation of classical number-theory algorithms.

nsync is a portable C library that provides a collection of advanced synchronization primitives designed to facilitate safe and efficient multithreaded programming. It offers reader-writer locks, condition variables, run-once initialization, waitable counters, and waitable bits for coordination and cancellation between threads. Unlike traditional pthreads-based synchronization, nsync introduces conditional critical sections, allowing developers to wait for arbitrary conditions without explicit signaling or complex loop-based logic. This approach simplifies concurrency management and often improves readability and maintainability of multithreaded code. The library emphasizes efficiency, with locks and condition variables occupying minimal memory and supporting cancellation mechanisms through nsync_note objects rather than thread-level cancellation. Designed with portability and performance in mind, nsync can be compiled on Unix-like systems and Windows using a C90 compiler.

liblzg is a minimal implementation of an LZ77 class compression library. The main characteristic of the library is that the decoding routine is very simple, fast and requires no memory.

libposix is a bold attempt to unify the impementation of the core functionality of all Unix systems. libposix is a full, cross platform, implementation of the POSIX 2008 standard written from scratch.
