Is there any data compression algorithm or library which can be run on M4 with less than 32KB RAM available?

It depends on what you want to compress. If it works, RLL is very compact.

Hi,

The MCU that is based on Cortex-M4 is the Tiva MCU (TM4C129 and TM4C123). There is no data compression library that comes with the SDK for these MCUs. I hope you can do some online searches for them and port to Tiva MCUs.
