Accuracy and efficiency of the energy measurement and reliability of pile-up suppression are substantial when processing the detector raw-data in real-time. Several digital filter algorithms are investigated for their performance to extract energies from incoming detector signals and for the needs of the future trigger system. The implementation of fast, resource economizing, parameter driven filter algorithms in a modern Virtex FPGA is presented.
