| 31 | \section{data order in 64bit address space} |
|---|
| 32 | |
|---|
| 33 | When data is input into Data-RAM by the DataGenerator, the data is fed in as words of 64bit. |
|---|
| 34 | |
|---|
| 35 | Each Event constists of an EventHeader, the so called ChannelData, and a small EventFooter. |
|---|
| 36 | Figure (\ref{64bitRAM}) shows how the data is stored as 64bit words in the DataRAM. |
|---|
| 37 | Assume the Event Start-Address beeing {\tt 0x2000} and each package of ChannelData consists 100 samples. |
|---|
| 38 | \\ \\ |
|---|
| 39 | \emph{Erklaeren, dass auch wenn nur ein channel kleiner ist, die selbe Anzahl Daten versendet wird.} |

| 88 | During DRS readout and data digitzation, the Trigger ID is coming in through RS485 interface from FTM board. |
|---|
| 89 | The Trigger ID reciption takes about $40 {\mu}$s. Therefor the 2 words containing Trigger information in the EventHeader are |
|---|
| 90 | left empty in the first place. The digitazed analog data is read in as quickly as possible. Only after finishing the Readout, |
|---|
| 91 | the Trigger ID is filled into the EventHeader. |
|---|
| 92 | Then the EventFooter is added and the Readout is finished. |
