3. Wrapping Event Builder Communications Input and Output to Event Builder are defined by I2O messages We want to encapsulate the buffering and I2O packing, unpacking, and message handling into a common FED class, so each subdetector can share it. –Avoids much duplicated code –Lets us change things easily STATUS: Being tested –Triggering not clear –Chamber and trackfinder events not one-to-one. EventReader EventWriter EmuFED GenericFEDEmuConfigFED xdaqApplication Event Builder

4. Local File Writing We need to write a stream of local data because: – Event rate very fast… not clear that the Event Builder can handle it. – Needs to be done for calibrations runs in the final system, anyway Status: Utilities written, but no XDAQ interface.

5. File Input to the Event Builder We do want to be able to combine chamber and trigger trackfinder data offline. Working on XDAQ application to control this

6. Interpreting the Data Format HardwareDDU FileReaderDDU DDU DDUEventData CSCEventData CFEBData ALCTData CLCTData Rick: built C++ objects from the big multidimensional arrays that come from Jason Gilmore’s C unpacking routines –Only DDU, DAQ motherboard, and cathode data, no LCT Alex: –Validation package –Organized data better –getting rid of the C vestiges. STATUS: Still need trigger motherboard data –Formats still stabilizing

7. ROOT Analysis Objects Will be based as closely as possible on the classes from the data unpacking –Maybe even using those classes themselves Pat will take the ROOT classes at CERN June 3-5, so that will be a good time to get questions answered.

9. Event Builder Output Format If we’re combining chamber and trackfinder data, we need a data format with things like event headers and readout headers Giacomo Bruno’s DaqPrototype package provides these, with the additional benefit of being ORCA-readable! STATUS: Being written
