LZMA provides a high compression ratio and fast decompression, so it is very suitable for embedded applications. For example, it can be used for ROM (firmware) compressing. LZMA SDK includes: <UL> <LI>C++ source code of LZMA Encoder and Decoder</LI> <LI>C++ source code for .7z compression and decompression (reduced version)</LI> <LI>ANSI-C compatible source code for LZMA / LZMA2 / XZ compression and decompression</LI> <LI>ANSI-C compatible source code for 7z decompression with example</LI> <LI>C# source code for LZMA compression and decompression</LI> <LI>Java source code for LZMA compression and decompression</LI> <LI>lzma.exe for .lzma compression and decompression</LI> <LI>7zr.exe to work with 7z archives (reduced version of 7z.exe from 7-Zip)</LI> <LI>SFX modules to create self-extracting packages and installers</LI> </UL> ANSI-C and C++ source code in LZMA SDK is subset of source code of 7-Zip. LZMA features: <UL> <LI>Compression speed: 2-8 MB/s on 4 GHz CPU using two cpu threads. <LI>Decompression speed on single cpu thread: <UL> <LI>30-100 MB/s on modern 4 GHz CPU (Intel, AMD, ARM). <LI>5-15 MB/s on simple 1 GHz RISC CPU (ARM, MIPS, PowerPC). </UL> <LI>Small memory requirements for decompression: 8-32 KB + DictionarySize <LI>Small code size for decompression: 2-8 KB (depending on speed optimizations) </UL> The LZMA decoder uses only CPU integer instructions and can be implemented for any modern 32-bit CPU. <H2>License</H2> LZMA SDK is placed in the public domain. Anyone is free to copy, modify, publish, use, compile, sell, or distribute the original LZMA SDK code, either in source code form or as a compiled binary, for any purpose, commercial or non-commercial, and by any means. <H2>LZMA Links</H2> <ul> <li><A href="https://en.wikipedia.org/wiki/LZMA">LZMA at Wikipedia</A></li> <li><a href="https://www.7-cpu.com/">LZMA Benchmark results for different CPUs</a></li> <li><a href="https://tukaani.org/xz/">XZ Utils / LZMA utils</a></li> <li><A href="https://sourceforge.net/projects/p7zip/">Port of LZMA SDK for JAVA from independent developer</A></li> <li><A href="https://www.birtles.org.uk/programming/">Port of LZMA SDK to Pascal (Delphi, Kylix and Freepascal)</A></li> <li><a href="https://www.joachim-bauch.de/projects/python/pylzma/">PyLZMA: Python bindings for LZMA</a></li> <li><a href="https://contrapunctus.net/league/haques/lzmajio/">LZMA Streams in Java</a></li> <li><a href="https://unzip-ada.sourceforge.io/">Zip-Ada : LZMA in Ada</a></li> </ul> <HR> Copyright (C) 2024 Igor Pavlov. </TD></TR></TABLE> </BODY></HTML>
