However, I wanted to provide also a low-level C library that advanced programmers could embed deep in their own software without the inconvenience of a bulky C++ research library.
So we wrote the SIMDComp library. It is a minimalist C library. On a recent PC, it will decompress integers at over 4 billion integers per second: less than one CPU cycle per integer. We use a liberal open source license so it should be suitable for all your projects.
To test it out for yourself, grab a copy, and type “make example; ./example”.
