Data Acquisition System for the COMPASS++/ AMBER Experiment

We present a new data acquisition system for the COMPASS++/AMBER experiment designed as further development of intelligent FPGA-based framework. The is to have maximum throughput 5 GB/s. provide free-running continuous readout, which allows us implement sophisticated filtering by delaying decision until hardware filter and high-level trigger stage processes data. includes front-end cards, fully digital filter, multiplexers, timeslice builder, farm. selection assembly require time structure streams with different granularity detectors. define unit detector image combine images from detectors within window timeslices. By routing based on timeslices, we can average rates easily achieve scalability. main component that these goals high-performance cost-effective builder. builder combines streaming their consists switch spillbuffer build. scalable architecture increase true triggerless mode operation.
