@oe1cxw @folknology Any ideas on the good #ice40 compression method with compact decompression library for ARM host?

Agree, 33% is a good start. Could you elaborate more on the algorithm your are using?
I am storing the distances between ones. I'm using a simple Huffman code to use fewer bits for small distances.

Out of curiosity: Could BDI make sense here at all or not? https://www.cs.cmu.edu/~gpekhime/Talks/BDI-Compression.pdf … / https://www.ece.cmu.edu/~safari/thesis/gpekhimenko_dissertation.pdf ….

the bitstream has well known word width format with regions of different size. Can compressor exploit it?
-
can we break bitsream into multiple bitsreams related to different FPGA resources and time-domain multiplexer stream.

does it mean that compressed all-ones stream will be bigger than original?

yes, this way you are winning allot on Zero and loosing on Ones. Here is 128'b1 example:pic.twitter.com/GxGyXZxqym
