If you want to add an new architecture (e.g. 78k as described below) then you have to find a binary, and extract the executable section (the command line to extract the 78k code from the Metz firmware ...

Abstract: In this paper, one of the constituent codes, Rate-1 node, is used to simplify Successive-Cancellation List (SCL) decoding of non-binary polar codes for reducing the decoding complexity.
