The header is included into the group of channels 0, while the package footer is included into group of channels 9. 358 358 359 In the next state called FIFO CALC. Here 360 361 359 \subsubsection{state: MM CONFIG} 360 Here all local variables are reset to zero. Let me shortly explain the meaning of each of them: 361 \begin{table}[htbp] 362 \begin{tabular}{lll} 363 roi\_max\_array & array (0 to 8) of integer range 0 to 1024 & maximum for each channel group\\ 364 channel\_size & array (0 to 8) of integer range 0 to W5300\_TX\_FIFO\_SIZE & size of each channel group in 16b words \\ 365 fifo\_write\_length & array (0 to 8) of integer range 0 to W5300\_TX\_FIFO\_SIZE & similar ??? \\ 366 fifo\_channels\_array & array (0 to 8) of integer range 0 to 9 & ??? \\ 367 \hline \\ 368 event_size & integer range 0 to RAM\_SIZE\_16B & ???\\ 369 event_size_ram & integer range 0 to RAM\_SIZE\_16B & ???\\ 370 event_size_ram_64b & integer range 0 to RAM\_SIZE\_64B & ??? \\ 371 \end {tabular} 372 \caption{ -no caption- -no label-} 373 %\label{} 374 \end{table} 375 376 The input is only: 377 \begin{table}[htbp] 378 \begin{tabular}{lll} 379 roi\_array & array (0 to 35) of integer range 0 to 1024 & ROI of each channel\\ 380 \end {tabular} 381 \caption{ -no caption- -no label-} 382 %\label{} 383 \end{table} 384 385 \subsubsection{states: MAX ROI\bf{n} and state: FIFO\_CALC} 386 \begin{itemize} 387 \item find maxium in roi\_array for each channel and store it as the maximum roi of each channel group inside roi\_max\_array. 388 \item calculate channel\_size(n) as $sum_{drs=0}^{3} \left( roi_{drs,n} + CHANNEL\_HEADER\_SIZE \right)$. 389 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. 390 So channel\_size(n) stores the number of 16bit words, which will be transmitted over ethernet for this particular group of channels n. \\ 391 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. 392 \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 393 fifo\_write\_length is a size measures in 16bit words, which will actually be transmitted over ethernet. 394 \end{itemize} 395 396 397 \subsubsection{states: RAM\_CALC\bf{n}} 398 Here we need to know how many of these packages will fit into our data RAM. 399 There 362 400 363 401 \end{document}
