LZMA SDK 9.20 ------------- LZMA SDK provides the documentation, samples, header files, libraries, and tools you need to develop applications that use LZMA compression. LZMA is default and general compression method of 7z format in 7-Zip compression program (www.7-zip.org). LZMA provides high compression ratio and very fast decompression. LZMA is an improved version of famous LZ77 compression algorithm. It was improved in way of maximum increasing of compression ratio, keeping high decompression speed and low memory requirements for decompressing. LICENSE ------- LZMA SDK is written and placed in the public domain by Igor Pavlov. Some code in LZMA SDK is based on public domain code from another developers: 1) PPMd var.H (2001): Dmitry Shkarin 2) SHA-256: Wei Dai (Crypto++ library) LZMA SDK Contents ----------------- LZMA SDK includes: - ANSI-C/C++/C#/Java source code for LZMA compressing and decompressing - Compiled file->file LZMA compressing/decompressing program for Windows system UNIX/Linux version ------------------ To compile C++ version of file->file LZMA encoding, go to directory CPP/7zip/Bundles/LzmaCon and call make to recompile it: make -f makefile.gcc clean all In some UNIX/Linux versions you must compile LZMA with static libraries.

Some critical operations that affect the speed of LZMA decompression: 1) 32*16 bit integer multiply 2) Misspredicted branches (penalty mostly depends from pipeline length) 3) 32-bit shift and arithmetic operations The speed of LZMA decompressing mostly depends from CPU speed. Memory speed has no big meaning. But if your CPU has small data cache, overall weight of memory speed will slightly increase. How To Use ---------- Using LZMA encoder/decoder executable -------------------------------------- Usage: LZMA <e|d> inputFile outputFile [<switches>...] e: encode file d: decode file b: Benchmark. There are two tests: compressing and decompressing with LZMA method. Benchmark shows rating in MIPS (million instructions per second). Rating value is calculated from measured speed and it is normalized with Intel's Core 2 results. Also Benchmark checks possible hardware errors (RAM errors in most cases). Benchmark uses these settings: (-a1, -d21, -fb32, -mfbt4). You can change only -d parameter. Also you can change the number of iterations. Example for 30 iterations: LZMA b 30 Default number of iterations is 10. <Switches> -a{N}: set compression mode 0 = fast, 1 = normal default: 1 (normal) d{N}: Sets Dictionary size - [0, 30], default: 23 (8MB) The maximum value for dictionary size is 1 GB = 2^30 bytes. Dictionary size is calculated as DictionarySize = 2^N bytes. For decompressing file compressed by LZMA method with dictionary size D = 2^N you need about D bytes of memory (RAM). -fb{N}: set number of fast bytes - [5, 273], default: 128 Usually big number gives a little bit better compression ratio and slower compression process. -lc{N}: set number of literal context bits - [0, 8], default: 3 Sometimes lc=4 gives gain for big files. -lp{N}: set number of literal pos bits - [0, 4], default: 0 lp switch is intended for periodical data when period is equal 2^N. For example, for 32-bit (4 bytes) periodical data you can use lp=2. Often it's better to set lc0, if you change lp switch. -pb{N}: set number of pos bits - [0, 4], default: 2 pb switch is intended for periodical data when period is equal 2^N. -mf{MF_ID}: set Match Finder. Default: bt4. Algorithms from hc* group doesn't provide good compression ratio, but they often works pretty fast in combination with fast mode (-a0). Memory requirements depend from dictionary size (parameter "d" in table below). MF_ID Memory Description bt2 d * 9.5 + 4
