A cross-platform, cross-compiler, cross-CPU C header library for programming with SIMD instruction sets. X86 (MMX/SSE/SSE2) GCC and MSVC, PPC Altivec GCC, WMMX ARM GCC, and software emulated SIMD are supported.
ArchAssembler is a .net (c#) library providing the functionalities of an assembler. Target architecture is x86/x64 with streaming SIMD extensions. Target executable file format is Windows Portable Executable (PE).
We want to remove the space (' ') and the line feeds characters ('\n', '\r') from a string as fast as possible. To avoid unnecessary allocations, we wish to do the processing in-place.Note that clang seems to give better results than gcc.
A research library with integer compression schemes. It is broadly applicable to the compression of arrays of 32-bit integers where most integers are small. The library seeks to exploit SIMD instructions (SSE) whenever possible.This library can decode at least 4 billions of compressed integers per second on most desktop or laptop processors. That is, it can decompress data at a rate of 15 GB/s. This is significantly faster than generic codecs like gzip, LZO, Snappy or LZ4.
As the name suggests, this is a C/C++ library for fast compression and intersection of lists of sorted integers using SIMD instructions. The library focuses on innovative techniques and very fast schemes, with particular attention to differential coding. It introduces new SIMD intersections schemes such as SIMD Galloping.This library can decode at least 4 billions of compressed integers per second on most desktop or laptop processors. That is, it can decompress data at a rate of 15 GB/s. This is significantly faster than generic codecs like gzip, LZO, Snappy or LZ4.
These functions compute fast successive differences, and recover the original values from the fast successive differences (i.e., they compute a prefix sum) using fast SIMD instructions.They can be useful as part of compressed index.
Various mathematical routines with SIMD acceleration (SSE/AVX/NEON) in the form of a compact C library. Designed without any OS portability in mind, tested only on Linux. Can work on BSD/Darwin after some potentially minor adaptation. Supports Android build / bionic.
