…LZ4 on the 65816 for the Apple IIgs with a decompressor that exploits that processor's block copy. https://github.com/emmanuel-marty/lzsa - LZSA - a LZ4-like modern LZ that's more efficient both in speed and compression to LZ4 (at least on…

…the PDP-11 code was even modelled after the 8086. Just convergent implementation?) Source here: https://github.com/emmanuel-marty/lzsa The only difference of note is the PDP-11 doesn't have string array operations (but it doesn't really…

This is basically an ad. The author of LZSA has a nice comparison that may help: https://github.com/emmanuel-marty/lzsa LZSA focuses on very fast decompression on 8-bit systems; so I suspect some of those could be used for MCUs as well,…
