Same conclusion as others: no source, no figures, TFA is basically an ad. There are already tools to compress on a PC and decompress on a small machine, with more-than-decent compression rate and decompression speed, for example Exomizer https://bitbucket.org/magli143/exomizer https://bitbucket.org/magli143/exomizer As an example, a decompression routine for the Z80 is about 154 bytes of code, needs 156 bytes of private data, and the decompression speed is not that much lower than a memory-to-memory copy speed. It even has options to ease the case when decompressing in the same memory range as the compressed data so that you can load data in RAM and decompress in-place. I actually used it in a project (not yet open-source, but based on my open-source framework https://github.com/cpcitor/cpc-dev-tool-chain https://github.com/cpcitor/cpc-dev-tool-chain which integrates exomizer).
