Experiments in subatomic physics have to handle data rates at several MHz per readout channel to reach statistical significance for the measured quantities. Frequently such experiments have to deal with fast signals which may cover large dynamic ranges. For applications which require amplitude as well as time measurements with highest accuracy transient recorders with very high resolution and deep on-board memory are the first choice. We have built a 16-channel 12-or14 bit single unit VME64x/VXS sampling ADC module which may sample at rates up to 1GS/s. Fast algorithms have been developed and successfully implemented for the readout of the recoil-proton detector at the COMPASS-II Experiment at CERN. We report on the implementation of the feature extraction algorithms and the performance achieved during a pilot with the COMPASS-II Experiment.
