Description
We present a new data acquisition system for
the COMPASS++/AMBER experiment designed as a further
development of the Intelligent FPGA-based Data Acquisition
framework. The system is designed to have a throughput of
5 GB/s. The system includes front-end cards, fully-digital trigger
processor, data multiplexers, data switch, an event builder, and
a PCIe interface to the PC for data storage. We designed the
system to provide free-running continuous read out. The free-
running continuous detector read out allows us to implement
a sophisticated triggering algorithms by delaying data filtering
until the event builder stage. The data selection and event
assembly then require a time structure of the data streams
with different granularity for different detectors. By routing data
based on the time structure we can average data rates on the
event builder inputs and easily achieve scalability. The scalable
architecture allows us to increase the throughput of the system
and achieve a true triggerless mode of operation.
