+\subsubsection{states: MAX ROI\bf{n} and state: FIFO\_CALC} 
+\begin{itemize}
+\item find maxium in roi\_array for each channel and store it as the maximum roi of each channel group inside roi\_max\_array.
+\item calculate channel\_size(n) as $sum_{drs=0}^{3} \left( roi_{drs,n} + CHANNEL\_HEADER\_SIZE \right)$. 
+For $n=0$ the size of the package header is added and for $n=8$ the size of the package footer is added to the channel\_size.
+So channel\_size(n) stores the number of 16bit words, which will be transmitted over ethernet for this particular group of channels n. \\
+Note: this is not the number of 16bit words, which will be stored inside the internal data RAM, since this number is defined by the maximum roi of each channel group.
+\item calculate into how many pieces the package need to be devided. fifo\_write\_length(m) contains a certain sum of channel\_sizes. So again
+fifo\_write\_length is a size measures in 16bit words, which will actually be transmitted over ethernet.

+\subsubsection{states: RAM\_CALC\bf{n}}
+Here we need to know how many of these packages will fit into our data RAM.
