The Train Builder collects all the fragments and reorganize them into a complete series of frames per train. It also allows online processing before transfer to the PC Layer. The Clock and Control System (based on the MicroTCA standard) allows synchronization, control, VETOing and status request of all detector tiles. The connected VETO system allows most efficient use of the limited storage capacity of the detectors and also allows data reduction in later stages to save bandwidth and storage for archiving. Simulink based FPGA Programming Framework Easy block based graphical interface Allows non-programmers design and simulation of algorithms Direct implementation in FPGA Availability of many tools (e.g. filter design) Overview of Data Acquisition (DAQ) electronics systems for Photon Beamlines and Experiments at the European XFEL P.

This is done via digitizers in MicroTCA standard, allowing complete data streaming and archiving as well as online processing on-board in FPGA, in a Train Builder (FPGA) or on GPUs and CPUs in the PC Layer.
