|
|---|
| 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.
