One of the major challenges in the operation of SO/PHI (PHI homepage) is the very low amount of telemetry available in orbit. To overcome this challenge we implemented a complex, autonomous on-board data processing system for instrument calibrations and science data processing. This system is distributed between software and hardware, integrating two Field Programmable Gate Arrays (FPGA-s), reconfigured in flight, to accelerate image processing operations. The software framework of the system implements a flexible environment, possible to use for numerous applications, coping with the resource limitations in space. The software framework was presented at the SPIE Astronomical Telescopes + Instrumentation 2018, from which the proceedings are referenced as: K. Albert, J. Hirzberger, D. Busse, T. Lange, M.
