Fast decompression and C portable library ?
category: code [glöplog]
Hi...
I checked the old threads, found some clues but not all...
I'm looking for a very fast (to keep up the framerate) decompression C-based library to run on MCUs (< 100 KB of RAM) to decrunch data (mostly images and sequence of images).
I found this cool website squash which looks to point me to lz4 and density but maybe there are some underground scene algorithms/depackers which my be better.
Any suggestion ?
Thanks!

LZSA was added to Pouet just recently, maybe it fits your bill?
Jup, LZSA looks promising.
In the last 15 years i primarily used pucrunch for such tasks on MCU, can recommend it!

underground scene algorithm :D

The Demoscene is dead, right ? :)

LZSS is not so bad at decompressing. For a MCU implementation take a look a heatshrink. There's also a lot of similar questions on stackoverflow you should read through.
Didn't know about LZSA. That thing looks great!

Where's that coming from now? ;)
just wanted to motivated someone to implement that mysterious "underground scene algorithm" and name it USA ;-)
