Open Source Assembly Libraries for ChromeOS

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.

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.

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.

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.

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.

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.
