-When data is input into Data-RAM by the DataGenerator, the data is fed in as words of 64bit,
-because the 13bits of each of the four ADCs is processed in a parallel manner.

 Each Event constists of an EventHeader, the so called ChannelData, and a small EventFooter.

-\subsection{role of memory manager for DataGenerator}
-After FAD-configuration memory manager informs data generator, whether additional Data may be read out or not.
