With the aim to build a real-time controlled time-of-flight Compton camera for an improved ion-range dose delivery control on hadrontherapy, as defined by the CLaRyS collaboration project, a programming data acquisition and slow control back-end electronics is necessary. This paper presents the FPGA based firmware architecture, embedded software and associated tools for the back-end electronics of CLaRyS, that is able to provide multiple 3 Gb/s optical links for data acquisition, trigger distribution and slow control over its detectors. Performance of the system based on simulations and analysis of the results acquired during the characterization of a beam hodoscope will be presented. Experiments were performed with the 65 MeV proton beam of the medical cyclotron at the Mediterranean Protontherapy Institute, in Nice.
