Compression algorithms sources great for commercial projects algorithm for PC and algorithm for AVR Description

Usage (algorithm 1, AVR). This algirithm designed for physical measurements data first, but I made it universal, so it compress any data that have anykind of regularities. Algorithm works extremelly fast (50 us for Initialization and about 1 us per compressed byte on Atmel 10 MHz processor) - there is no cycles or recursion in algorithm, except initialization cycle. This algorithm don't give high compression ratio, no more, than 3 times compression. Of course, there are realizations of this algorithm in C and in AVR ASM. It is possible to compress data in microcontroller and to decompress it on PC. Usage (algorithm 2). This algorithm able to compress with ratio 12 and even more. It is faster (sometimes few times faster), than ZIP. Good for databases, text, music, graphic. Originally this compression algorithm used in big programming product (that is database system like Oracle is) to compress (when making export) and decompress (when making import) data. I'm the author of this code, so I changed it a little and translated it to Turbo Pascal. There are versions for Turbo Pascal, Borland C, C++, Visual C++ (or any other C++, like gcc). I'm sure that there are no bugs in it. Platforms supported:Windows 95, MS DOS, Unix / Linux, Windows NT, Windows 2000, Windows XP, Windows 98, Windows ME
