-LZMA is the default and general compression method of 7z format
+
LZMA / LZMA2 are default and general compression methods of 7z format
in the 7-Zip program. LZMA provides a high compression ratio and
-very fast decompression, so it is very suitable for embedded applications.
+fast decompression, so it is very suitable for embedded applications.
For example, it can be used for ROM (firmware) compressing.
LZMA SDK includes:
- C++ source code of LZMA Encoder and Decoder
- - ANSI-C compatible source code for LZMA decompression with example
+ - C++ source code for .7z compression and decompression (reduced version)
+ - ANSI-C compatible source code for LZMA / LZMA2 / XZ compression and decompression
+ - ANSI-C compatible source code for 7z decompression with example
- C# source code for LZMA compression and decompression
- Java source code for LZMA compression and decompression
- - Compiled file->file LZMA compression/decompression program for the Windows operating system
+ - lzma.exe for .lzma compression and decompression
+ - 7zr.exe to work with 7z archives (reduced version of 7z.exe from 7-Zip)
+ - SFX modules to create self-extracting packages and installers
-ANSI-C LZMA decompression code is ported from the original C++ sources to C.
-Also, it has been simplified and optimized for code size. But it is fully compatible
-with LZMA from 7-Zip.
+ANSI-C and C++ source code in LZMA SDK is subset of source code of 7-Zip.
LZMA features:
- - Compression speed: 2 MB/s on 2 GHz dual-core CPU.
+
- Compression speed: 3 MB/s on 3 GHz dual-core CPU.
- Decompression speed:
- - 20-30 MB/s on 2 GHz Intel Core2 or AMD Athlon 64.
-
- 1-2 MB/s on 200 MHz ARM, MIPS, PowerPC or other simple RISC CPU.
+
- 20-50 MB/s on modern 3 GHz CPU (Intel, AMD, ARM).
+
- 5-15 MB/s on simple 1 GHz RISC CPU (ARM, MIPS, PowerPC).
- Small memory requirements for decompression: 8-32 KB + DictionarySize
- Small code size for decompression: 2-8 KB (depending on speed optimizations)
The LZMA decoder uses only CPU integer instructions and can be
-implemented for any modern 32-bit CPU (or, on a 16-bit CPU with some conditions).

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.
